A local user could use a thread running with a stale cached virtual->physical translation to potentially escalate their privileges if the translation in question were writable and the physical page got reused for something critical (for example, a page table).\n(CVE-2016-2069, Moderate)\n\n* A race condition flaw was found in the ioctl_send_fib() function in the Linux kernel's aacraid implementation.

(CVE-2016-6480, Moderate)\n\n* It was found that when the gcc stack protector was enabled, reading the /proc/keys file could cause a panic in the Linux kernel due to stack corruption. This happened because an incorrect buffer size was used to hold a 64-bit timeout value rendered as weeks.

(CVE-2016-10142,\n Moderate)\n\n - A flaw was discovered in the way the Linux kernel dealt\n with paging structures. When the kernel invalidated a\n paging structure that was not in use locally, it could,\n in principle, race against another CPU that is switching\n to a process that uses the paging structure in question.\n A local user could use a thread running with a stale\n cached virtual->physical translation to potentially\n escalate their privileges if the translation in question\n were writable and the physical page got reused for\n something critical (for example, a page table).\n (CVE-2016-2069, Moderate)\n\n - A race condition flaw was found in the ioctl_send_fib()\n function in the Linux kernel's aacraid implementation. A\n local attacker could use this flaw to cause a denial of\n service (out-of-bounds access or system crash) by\n changing a certain size value. (CVE-2016-6480, Moderate)\n\n - It was found that when the gcc stack protector was\n enabled, reading the /proc/keys file could cause a panic\n in the Linux kernel due to stack corruption.

A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.\n\nThe kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.\n\nSecurity Fix(es) :\n\n* Out-of-bounds kernel heap access vulnerability was found in xfrm, kernel's IP framework for transforming packets. An error dealing with netlink messages from an unprivileged user leads to arbitrary read/write and privilege escalation. (CVE-2017-7184, Important)\n\n* A race condition issue leading to a use-after-free flaw was found in the way the raw packet sockets are implemented in the Linux kernel networking subsystem handling synchronization. A local user able to open a raw packet socket (requires the CAP_NET_RAW capability) could use this flaw to elevate their privileges on the system.\n(CVE-2017-1000111, Important)\n\n* An exploitable memory corruption flaw was found in the Linux kernel.\nThe append path can be erroneously switched from UFO to non-UFO in ip_ufo_append_data() when building an UFO packet with MSG_MORE option.\nIf unprivileged user namespaces are available, this flaw can be exploited to gain root privileges. (CVE-2017-1000112, Important)\n\n* A flaw was found in the Linux networking subsystem where a local attacker with CAP_NET_ADMIN capabilities could cause an out-of-bounds memory access by creating a smaller-than-expected ICMP header and sending to its destination via sendto(). (CVE-2016-8399, Moderate)\n\n* Kernel memory corruption due to a buffer overflow was found in brcmf_cfg80211_mgmt_tx() function in Linux kernels from v3.9-rc1 to v4.13-rc1. The vulnerability can be triggered by sending a crafted NL80211_CMD_FRAME packet via netlink. This flaw is unlikely to be triggered remotely as certain userspace code is needed for this. An unprivileged local user could use this flaw to induce kernel memory corruption on the system, leading to a crash. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although it is unlikely. (CVE-2017-7541, Moderate)\n\n* An integer overflow vulnerability in ip6_find_1stfragopt() function was found. A local attacker that has privileges (of CAP_NET_RAW) to open raw socket can cause an infinite loop inside the ip6_find_1stfragopt() function. (CVE-2017-7542, Moderate)\n\n* A kernel data leak due to an out-of-bound read was found in the Linux kernel in inet_diag_msg_sctp{,l}addr_fill() and sctp_get_sctp_info() functions present since version 4.7-rc1 through version 4.13. A data leak happens when these functions fill in sockaddr data structures used to export socket's diagnostic information. As a result, up to 100 bytes of the slab data could be leaked to a userspace. (CVE-2017-7558, Moderate)\n\n* The mq_notify function in the Linux kernel through 4.11.9 does not set the sock pointer to NULL upon entry into the retry logic. During a user-space close of a Netlink socket, it allows attackers to possibly cause a situation where a value may be used after being freed (use-after-free) which may lead to memory corruption or other unspecified other impact. (CVE-2017-11176, Moderate)\n\n* A divide-by-zero vulnerability was found in the __tcp_select_window function in the Linux kernel. This can result in a kernel panic causing a local denial of service.

A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.\n\nThe kernel packages contain the Linux kernel, the core of any Linux operating system.\n\nSecurity Fix(es) :\n\n* Out-of-bounds kernel heap access vulnerability was found in xfrm, kernel's IP framework for transforming packets. An error dealing with netlink messages from an unprivileged user leads to arbitrary read/write and privilege escalation. (CVE-2017-7184, Important)\n\n* A race condition issue leading to a use-after-free flaw was found in the way the raw packet sockets are implemented in the Linux kernel networking subsystem handling synchronization. A local user able to open a raw packet socket (requires the CAP_NET_RAW capability) could use this flaw to elevate their privileges on the system.\n(CVE-2017-1000111, Important)\n\n* An exploitable memory corruption flaw was found in the Linux kernel.\nThe append path can be erroneously switched from UFO to non-UFO in ip_ufo_append_data() when building an UFO packet with MSG_MORE option.\nIf unprivileged user namespaces are available, this flaw can be exploited to gain root privileges. (CVE-2017-1000112, Important)\n\n* A flaw was found in the Linux networking subsystem where a local attacker with CAP_NET_ADMIN capabilities could cause an out-of-bounds memory access by creating a smaller-than-expected ICMP header and sending to its destination via sendto(). (CVE-2016-8399, Moderate)\n\n* Kernel memory corruption due to a buffer overflow was found in brcmf_cfg80211_mgmt_tx() function in Linux kernels from v3.9-rc1 to v4.13-rc1. The vulnerability can be triggered by sending a crafted NL80211_CMD_FRAME packet via netlink. This flaw is unlikely to be triggered remotely as certain userspace code is needed for this. An unprivileged local user could use this flaw to induce kernel memory corruption on the system, leading to a crash. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although it is unlikely. (CVE-2017-7541, Moderate)\n\n* An integer overflow vulnerability in ip6_find_1stfragopt() function was found. A local attacker that has privileges (of CAP_NET_RAW) to open raw socket can cause an infinite loop inside the ip6_find_1stfragopt() function. (CVE-2017-7542, Moderate)\n\n* A kernel data leak due to an out-of-bound read was found in the Linux kernel in inet_diag_msg_sctp{,l}addr_fill() and sctp_get_sctp_info() functions present since version 4.7-rc1 through version 4.13. A data leak happens when these functions fill in sockaddr data structures used to export socket's diagnostic information. As a result, up to 100 bytes of the slab data could be leaked to a userspace. (CVE-2017-7558, Moderate)\n\n* The mq_notify function in the Linux kernel through 4.11.9 does not set the sock pointer to NULL upon entry into the retry logic. During a user-space close of a Netlink socket, it allows attackers to possibly cause a situation where a value may be used after being freed (use-after-free) which may lead to memory corruption or other unspecified other impact. (CVE-2017-11176, Moderate)\n\n* A divide-by-zero vulnerability was found in the __tcp_select_window function in the Linux kernel. This can result in a kernel panic causing a local denial of service. (CVE-2017-14106, Moderate)\n\nRed Hat would like to thank Chaitin Security Research Lab for reporting CVE-2017-7184; Willem de Bruijn for reporting CVE-2017-1000111; and Andrey Konovalov for reporting CVE-2017-1000112.\nThe CVE-2017-7558 issue was discovered by Stefano Brivio (Red Hat).\n\nSpace precludes documenting all of the bug fixes and enhancements included in this advisory.

Versions: Kernel-3.10, Kernel-3.18. Android ID:\n A-31349935. (CVE-2016-8399)\n\n - An issue was discovered in the IPv6 protocol specification, related to ICMP Packet Too Big (PTB) messages.\n (The scope of this CVE is all affected IPv6 implementations from all vendors.) The security implications of IP fragmentation have been discussed at length in [RFC6274] and [RFC7739]. An attacker can leverage the generation of IPv6 atomic fragments to trigger the use of fragmentation in an arbitrary IPv6 flow (in scenarios in which actual fragmentation of packets is not needed) and can subsequently perform any type of fragmentation-based attack against legacy IPv6 nodes that do not implement [RFC6946]. That is, employing fragmentation where not actually needed allows for fragmentation-based attack vectors to be employed, unnecessarily. We note that, unfortunately, even nodes that already implement [RFC6946] can be subject to DoS attacks as a result of the generation of IPv6 atomic fragments. Let us assume that Host A is communicating with Host B and that, as a result of the widespread dropping of IPv6 packets that contain extension headers (including fragmentation) [RFC7872], some intermediate node filters fragments between Host B and Host A. If an attacker sends a forged ICMPv6 PTB error message to Host B, reporting an MTU smaller than 1280, this will trigger the generation of IPv6 atomic fragments from that moment on (as required by [RFC2460]). When Host B starts sending IPv6 atomic fragments (in response to the received ICMPv6 PTB error message), these packets will be dropped, since we previously noted that IPv6 packets with extension headers were being dropped between Host B and Host A. Thus, this situation will result in a DoS scenario. Another possible scenario is that in which two BGP peers are employing IPv6 transport and they implement Access Control Lists (ACLs) to drop IPv6 fragments (to avoid control-plane attacks). If the aforementioned BGP peers drop IPv6 fragments but still honor received ICMPv6 PTB error messages, an attacker could easily attack the corresponding peering session by simply sending an ICMPv6 PTB message with a reported MTU smaller than 1280 bytes. Once the attack packet has been sent, the aforementioned routers will themselves be the ones dropping their own traffic.

Let us assume that Host A is\n communicating with Host B and that, as a result of the widespread dropping of IPv6 packets that contain\n extension headers (including fragmentation) [RFC7872], some intermediate node filters fragments between\n Host B and Host A. If an attacker sends a forged ICMPv6 PTB error message to Host B, reporting an MTU\n smaller than 1280, this will trigger the generation of IPv6 atomic fragments from that moment on (as\n required by [RFC2460]). When Host B starts sending IPv6 atomic fragments (in response to the received\n ICMPv6 PTB error message), these packets will be dropped, since we previously noted that IPv6 packets with\n extension headers were being dropped between Host B and Host A. Thus, this situation will result in a DoS\n scenario. Another possible scenario is that in which two BGP peers are employing IPv6 transport and they\n implement Access Control Lists (ACLs) to drop IPv6 fragments (to avoid control-plane attacks). If the\n aforementioned BGP peers drop IPv6 fragments but still honor received ICMPv6 PTB error messages, an\n attacker could easily attack the corresponding peering session by simply sending an ICMPv6 PTB message\n with a reported MTU smaller than 1280 bytes. Once the attack packet has been sent, the aforementioned\n routers will themselves be the ones dropping their own traffic.

A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.\n\nThe kernel packages contain the Linux kernel, the core of any Linux operating system.\n\nSecurity Fix(es) :\n\n* It was discovered that a remote attacker could leverage the generation of IPv6 atomic fragments to trigger the use of fragmentation in an arbitrary IPv6 flow (in scenarios in which actual fragmentation of packets is not needed) and could subsequently perform any type of a fragmentation-based attack against legacy IPv6 nodes that do not implement RFC6946. (CVE-2016-10142, Moderate)\n\n* A flaw was discovered in the way the Linux kernel dealt with paging structures. When the kernel invalidated a paging structure that was not in use locally, it could, in principle, race against another CPU that is switching to a process that uses the paging structure in question. A local user could use a thread running with a stale cached virtual->physical translation to potentially escalate their privileges if the translation in question were writable and the physical page got reused for something critical (for example, a page table).\n(CVE-2016-2069, Moderate)\n\n* A race condition flaw was found in the ioctl_send_fib() function in the Linux kernel's aacraid implementation. A local attacker could use this flaw to cause a denial of service (out-of-bounds access or system crash) by changing a certain size value. (CVE-2016-6480, Moderate)\n\n* It was found that when the gcc stack protector was enabled, reading the / proc/keys file could cause a panic in the Linux kernel due to stack corruption. This happened because an incorrect buffer size was used to hold a 64-bit timeout value rendered as weeks. (CVE-2016-7042, Moderate)\n\n* It was found that when file permissions were modified via chmod and the user modifying them was not in the owning group or capable of CAP_FSETID, the setgid bit would be cleared. Setting a POSIX ACL via setxattr sets the file permissions as well as the new ACL, but doesn't clear the setgid bit in a similar way. This could allow a local user to gain group privileges via certain setgid applications.\n(CVE-2016-7097, Moderate)\n\n* A flaw was found in the Linux networking subsystem where a local attacker with CAP_NET_ADMIN capabilities could cause an out-of-bounds memory access by creating a smaller-than-expected ICMP header and sending to its destination via sendto(). (CVE-2016-8399, Moderate)\n\n* It was found that the blk_rq_map_user_iov() function in the Linux kernel's block device implementation did not properly restrict the type of iterator, which could allow a local attacker to read or write to arbitrary kernel memory locations or cause a denial of service (use-after-free) by leveraging write access to a /dev/sg device.\n(CVE-2016-9576, CVE-2016-10088, Moderate)\n\n* A flaw was found in the USB-MIDI Linux kernel driver: a double-free error could be triggered for the 'umidi' object.

elevation of privilege vulnerability in the kernel networking subsystem could enable a local malicious application to execute arbitrary code within the context of the kernel. This issue is rated as Moderate because it first requires compromising a privileged process and current compiler optimizations restrict access to the vulnerable code. Product: Android. Versions: Kernel-3.10, Kernel-3.18. Android ID:\n A-31349935. (CVE-2016-8399)\n\n - The xfrm_replay_verify_len function in net/xfrm/xfrm_user.c in the Linux kernel through 4.10.6 does not validate certain size data after an XFRM_MSG_NEWAE update, which allows local users to obtain root privileges or cause a denial of service (heap-based out-of-bounds access) by leveraging the CAP_NET_ADMIN capability, as demonstrated during a Pwn2Own competition at CanSecWest 2017 for the Ubuntu 16.10 linux- image-* package 4.8.0.41.52. (CVE-2017-7184)\n\n - The brcmf_cfg80211_mgmt_tx function in drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c in the Linux kernel before 4.12.3 allows local users to cause a denial of service (buffer overflow and system crash) or possibly gain privileges via a crafted NL80211_CMD_FRAME Netlink packet. (CVE-2017-7541)\n\n - Linux kernel: heap out-of-bounds in AF_PACKET sockets. This new issue is analogous to previously disclosed CVE-2016-8655. In both cases, a socket option that changes socket state may race with safety checks in packet_set_ring. Previously with PACKET_VERSION. This time with PACKET_RESERVE. The solution is similar:\n lock the socket for the update. This issue may be exploitable, we did not investigate further. As this issue affects PF_PACKET sockets, it requires CAP_NET_RAW in the process namespace. But note that with user namespaces enabled, any process can create a namespace in which it has CAP_NET_RAW. (CVE-2017-1000111)\n\n - The tcp_disconnect function in net/ipv4/tcp.c in the Linux kernel before 4.12 allows local users to cause a denial of service (__tcp_select_window divide-by-zero error and system crash) by triggering a disconnect within a certain tcp_recvmsg code path. (CVE-2017-14106)\n\n - Linux kernel: Exploitable memory corruption due to UFO to non-UFO path switch. When building a UFO packet with MSG_MORE __ip_append_data() calls ip_ufo_append_data() to append. However in between two send() calls, the append path can be switched from UFO to non-UFO one, which leads to a memory corruption. In case UFO packet lengths exceeds MTU, copy = maxfraglen - skb->len becomes negative on the non-UFO path and the branch to allocate new skb is taken. This triggers fragmentation and computation of fraggap = skb_prev->len - maxfraglen. Fraggap can exceed MTU, causing copy = datalen - transhdrlen - fraggap to become negative. Subsequently skb_copy_and_csum_bits() writes out-of-bounds. A similar issue is present in IPv6 code. The bug was introduced in e89e9cf539a2 ([IPv4/IPv6]: UFO Scatter-gather approach) on Oct 18 2005. (CVE-2017-1000112)\n\n - The mq_notify function in the Linux kernel through 4.11.9 does not set the sock pointer to NULL upon entry into the retry logic. During a user-space close of a Netlink socket, it allows attackers to cause a denial of service (use-after-free) or possibly have unspecified other impact. (CVE-2017-11176)\n\n - The ip6_find_1stfragopt function in net/ipv6/output_core.c in the Linux kernel through 4.12.3 allows local users to cause a denial of service (integer overflow and infinite loop) by leveraging the ability to open a raw socket. (CVE-2017-7542)\n\n - A kernel data leak due to an out-of-bound read was found in the Linux kernel in inet_diag_msg_sctp{,l}addr_fill() and sctp_get_sctp_info() functions present since version 4.7-rc1 through version 4.13. A data leak happens when these functions fill in sockaddr data structures used to export socket's diagnostic information. As a result, up to 100 bytes of the slab data could be leaked to a userspace.

the parallels-server-bm-release / vzkernel / etc packages installed, the Virtuozzo installation on the remote host is affected by the following vulnerabilities :\n\n - A flaw was found in the Linux kernel's handling of packets with the URG flag. Applications using the splice() and tcp_splice_read() functionality can allow a remote attacker to force the kernel to enter a condition in which it can loop indefinitely.\n\n - It was discovered that a remote attacker could leverage the generation of IPv6 atomic fragments to trigger the use of fragmentation in an arbitrary IPv6 flow (in scenarios in which actual fragmentation of packets is not needed) and could subsequently perform any type of a fragmentation-based attack against legacy IPv6 nodes that do not implement RFC6946.\n\n - It was found that the blk_rq_map_user_iov() function in the Linux kernel's block device implementation did not properly restrict the type of iterator, which could allow a local attacker to read or write to arbitrary kernel memory locations or cause a denial of service (use-after-free) by leveraging write access to a /dev/sg device.\n\n - A flaw was found in the Linux kernel's implementation of the SCTP protocol. A remote attacker could trigger an out-of-bounds read with an offset of up to 64kB potentially causing the system to crash.\n\n - A flaw was found in the Linux networking subsystem where a local attacker with CAP_NET_ADMIN capabilities could cause an out-of-bounds memory access by creating a smaller-than-expected ICMP header and sending to its destination via sendto().\n\n - It was found that when file permissions were modified via chmod and the user modifying them was not in the owning group or capable of CAP_FSETID, the setgid bit would be cleared. Setting a POSIX ACL via setxattr sets the file permissions as well as the new ACL, but doesn't clear the setgid bit in a similar way. This could allow a local user to gain group privileges via certain setgid applications.\n\n - It was found that when the gcc stack protector was enabled, reading the /proc/keys file could cause a panic in the Linux kernel due to stack corruption. This happened because an incorrect buffer size was used to hold a 64-bit timeout value rendered as weeks.\n\n - A race condition flaw was found in the ioctl_send_fib() function in the Linux kernel's aacraid implementation.\n A local attacker could use this flaw to cause a denial of service (out-of-bounds access or system crash) by changing a certain size value.\n\n - When creating audit records for parameters to executed children processes, an attacker can convince the Linux kernel audit subsystem can create corrupt records which may allow an attacker to misrepresent or evade logging of executing commands.\n\n - A flaw was discovered in the way the Linux kernel dealt with paging structures. When the kernel invalidated a paging structure that was not in use locally, it could, in principle, race against another CPU that is switching to a process that uses the paging structure in question. A local user could use a thread running with a stale cached virtual->physical translation to potentially escalate their privileges if the translation in question were writable and the physical page got reused for something critical (for example, a page table).\n\n - A flaw was found in the USB-MIDI Linux kernel driver: a double-free error could be triggered for the 'umidi' object.

An attacker with physical access to the system\n could use this flaw to escalate their privileges.\n\nNote that Tenable Network Security has extracted the preceding\ndescription block directly from the Virtuozzo security advisory.\nTenable has attempted to automatically clean and format it as much as\npossible without introducing additional issues.\");\n script_set_attribute(attribute:\"see_also\", value:\"https://help.virtuozzo.com/customer/portal/articles/2777857\");\n script_set_attribute(attribute:\"see_also\", value:\"https://rhn.redhat.com/errata/RHSA-2016-2766.html\");\n script_set_attribute(attribute:\"see_also\", value:\"https://rhn.redhat.com/errata/RHSA-2017-0036.html\");\n script_set_attribute(attribute:\"see_also\", value:\"https://rhn.redhat.com/errata/RHSA-2017-0293.html\");\n script_set_attribute(attribute:\"see_also\", value:\"https://rhn.redhat.com/errata/RHSA-2017-0307.html\");\n script_set_attribute(attribute:\"see_also\", value:\"https://rhn.redhat.com/errata/RHSA-2017-0817.html\");\n script_set_attribute(attribute:\"solution\", value:\n\"Update the affected parallels-server-bm-release / vzkernel / etc packages.\");\n script_set_cvss_base_vector(\"CVSS2#AV:N/AC:L/Au:N/C:C/I:C/A:C\");\n script_set_cvss_temporal_vector(\"CVSS2#E:H/RL:OF/RC:C\");\n script_set_cvss3_base_vector(\"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H\");\n script_set_cvss3_temporal_vector(\"CVSS:3.0/E:H/RL:O/RC:C\");\n script_set_attribute(attribute:\"exploitability_ease\", value:\"Exploits are available\");\n script_set_attribute(attribute:\"exploit_available\", value:\"true\");\n script_set_attribute(attribute:\"exploited_by_malware\", value:\"true\");\n\n script_set_attribute(attribute:\"patch_publication_date\", value:\"2017/03/30\");\n script_set_attribute(attribute:\"plugin_publication_date\", value:\"2017/03/31\");\n\n script_set_attribute(attribute:\"plugin_type\", value:\"local\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:virtuozzo:virtuozzo:parallels-server-bm-release\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:virtuozzo:virtuozzo:vzkernel\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:virtuozzo:virtuozzo:vzkernel-devel\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:virtuozzo:virtuozzo:vzkernel-firmware\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:virtuozzo:virtuozzo:vzmodules\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:virtuozzo:virtuozzo:vzmodules-devel\");\n script_set_attribute(attribute:\"cpe\", value:\"cpe:/o:virtuozzo:virtuozzo:6\");\n script_set_attribute(attribute:\"generated_plugin\", value:\"current\");\n script_end_attributes();\n\n script_category(ACT_GATHER_INFO);\n script_family(english:\"Virtuozzo Local Security Checks\");\n\n script_copyright(english:\"This script is Copyright (C) 2017-2021 and is owned by Tenable, Inc. or an Affiliate thereof.\");\n\n script_dependencies(\"ssh_get_info.nasl\");\n script_require_keys(\"Host/local_checks_enabled\", \"Host/Virtuozzo/release\", \"Host/Virtuozzo/rpm-list\");\n\n exit(0);\n}\n\ninclude(\"audit.inc\");\ninclude(\"global_settings.inc\");\ninclude(\"rpm.inc\");\n\nif (!get_kb_item(\"Host/local_checks_enabled\")) audit(AUDIT_LOCAL_CHECKS_NOT_ENABLED);\n\nrelease = get_kb_item(\"Host/Virtuozzo/release\");\nif (isnull(release) || \"Virtuozzo\" >!< release) audit(AUDIT_OS_NOT, \"Virtuozzo\");\nos_ver = pregmatch(pattern: \"Virtuozzo Linux release ([0-9]+\\.[0-9])(\\D|$)\", string:release);\nif (isnull(os_ver)) audit(AUDIT_UNKNOWN_APP_VER, \"Virtuozzo\");\nos_ver = os_ver[1];\nif (! preg(pattern:\"^6([^0-9]|$)\", string:os_ver)) audit(AUDIT_OS_NOT, \"Virtuozzo 6.x\", \"Virtuozzo \" + os_ver);\n\nif (!get_kb_item(\"Host/Virtuozzo/rpm-list\")) audit(AUDIT_PACKAGE_LIST_MISSING);\n\ncpu = get_kb_item(\"Host/cpu\");\nif (isnull(cpu)) audit(AUDIT_UNKNOWN_ARCH);\nif (\"x86_64\" >!< cpu && cpu !~ \"^i[3-6]86$\") audit(AUDIT_LOCAL_CHECKS_NOT_IMPLEMENTED, \"Virtuozzo\", cpu);\n\nflag = 0;\n\npkgs = [\"parallels-server-bm-release-6.0.12-3674\",\n \"vzkernel-2.6.32-042stab123.1\",\n \"vzkernel-devel-2.6.32-042stab123.1\",\n \"vzkernel-firmware-2.6.32-042stab123.1\",\n \"vzmodules-2.6.32-042stab123.1\",\n \"vzmodules-devel-2.6.32-042stab123.1\"];\n\nforeach (pkg in pkgs)\n if (rpm_check(release:\"Virtuozzo-6\", reference:pkg)) flag++;\n\nif (flag)\n{\n security_report_v4(\n port : 0,\n severity : SECURITY_HOLE,\n extra : rpm_report_get()\n );\n exit(0);\n}\nelse\n{\n tested = pkg_tests_get();\n if (tested) audit(AUDIT_PACKAGE_NOT_AFFECTED, tested);\n else audit(AUDIT_PACKAGE_NOT_INSTALLED, \"parallels-server-bm-release / vzkernel / etc\");\n}\n", "cvss": {"score": 10.0, "vector": "AV:N/AC:L/Au:N/C:C/I:C/A:C"}}, {"lastseen": "2023-02-17T15:23:26", "description": "The remote OracleVM system is missing necessary patches to address critical security updates :\n\n -

The bpf_int_jit_compile function in arch/x86/net/bpf_jit_comp.c in the Linux kernel before 4.0.6 allows local users to cause a denial of service (system crash) by creating a packet filter and then loading crafted BPF instructions that trigger late convergence by the JIT compiler. (CVE-2015-4700)\n\n - The sg implementation in the Linux kernel through 4.9 does not properly restrict write operations in situations where the KERNEL_DS option is set, which allows local users to read or write to arbitrary kernel memory locations or cause a denial of service (use-after-free) by leveraging access to a /dev/sg device, related to block/bsg.c and drivers/scsi/sg.c. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-9576. (CVE-2016-10088)\n\n - An elevation of privilege vulnerability in the kernel networking subsystem could enable a local malicious application to execute arbitrary code within the context of the kernel. This issue is rated as Moderate because it first requires compromising a privileged process and current compiler optimizations restrict access to the vulnerable code. Product: Android. Versions: Kernel-3.10, Kernel-3.18. Android ID:\n A-31349935. (CVE-2016-8399)\n\n - An issue was discovered in the IPv6 protocol specification, related to ICMP Packet Too Big (PTB) messages.\n (The scope of this CVE is all affected IPv6 implementations from all vendors.) The security implications of IP fragmentation have been discussed at length in [RFC6274] and [RFC7739]. An attacker can leverage the generation of IPv6 atomic fragments to trigger the use of fragmentation in an arbitrary IPv6 flow (in scenarios in which actual fragmentation of packets is not needed) and can subsequently perform any type of fragmentation-based attack against legacy IPv6 nodes that do not implement [RFC6946]. That is, employing fragmentation where not actually needed allows for fragmentation-based attack vectors to be employed, unnecessarily. We note that, unfortunately, even nodes that already implement [RFC6946] can be subject to DoS attacks as a result of the generation of IPv6 atomic fragments. Let us assume that Host A is communicating with Host B and that, as a result of the widespread dropping of IPv6 packets that contain extension headers (including fragmentation) [RFC7872], some intermediate node filters fragments between Host B and Host A. If an attacker sends a forged ICMPv6 PTB error message to Host B, reporting an MTU smaller than 1280, this will trigger the generation of IPv6 atomic fragments from that moment on (as required by [RFC2460]). When Host B starts sending IPv6 atomic fragments (in response to the received ICMPv6 PTB error message), these packets will be dropped, since we previously noted that IPv6 packets with extension headers were being dropped between Host B and Host A. Thus, this situation will result in a DoS scenario. Another possible scenario is that in which two BGP peers are employing IPv6 transport and they implement Access Control Lists (ACLs) to drop IPv6 fragments (to avoid control-plane attacks). If the aforementioned BGP peers drop IPv6 fragments but still honor received ICMPv6 PTB error messages, an attacker could easily attack the corresponding peering session by simply sending an ICMPv6 PTB message with a reported MTU smaller than 1280 bytes. Once the attack packet has been sent, the aforementioned routers will themselves be the ones dropping their own traffic. (CVE-2016-10142)\n\n - The sg_ioctl function in drivers/scsi/sg.c in the Linux kernel through 4.10.4 allows local users to cause a denial of service (stack-based buffer overflow) or possibly have unspecified other impact via a large command size in an SG_NEXT_CMD_LEN ioctl call, leading to out-of-bounds write access in the sg_write function. (CVE-2017-7187)\n\n - Race condition in drivers/tty/n_hdlc.c in the Linux kernel through 4.10.1 allows local users to gain privileges or cause a denial of service (double free) by setting the HDLC line discipline. (CVE-2017-2636)\n\n - The arcmsr_iop_message_xfer function in drivers/scsi/arcmsr/arcmsr_hba.c in the Linux kernel through 4.8.2 does not restrict a certain length field, which allows local users to gain privileges or cause a denial of service (heap-based buffer overflow) via an ARCMSR_MESSAGE_WRITE_WQBUFFER control code. (CVE-2016-7425)\n\n - The x25_negotiate_facilities function in net/x25/x25_facilities.c in the Linux kernel before 4.5.5 does not properly initialize a certain data structure, which allows attackers to obtain sensitive information from kernel stack memory via an X.25 Call Request. (CVE-2016-4580)\n\n - drivers/firewire/net.c in the Linux kernel before 4.8.7, in certain unusual hardware configurations, allows remote attackers to execute arbitrary code via crafted fragmented packets.

Versions: Kernel-3.10, Kernel-3.18. Android ID:\n A-31349935. (CVE-2016-8399)\n\n - An issue was discovered in the IPv6 protocol specification, related to ICMP Packet Too Big (PTB) messages.\n (The scope of this CVE is all affected IPv6 implementations from all vendors.) The security implications\n of IP fragmentation have been discussed at length in [RFC6274] and [RFC7739]. An attacker can leverage the\n generation of IPv6 atomic fragments to trigger the use of fragmentation in an arbitrary IPv6 flow (in\n scenarios in which actual fragmentation of packets is not needed) and can subsequently perform any type of\n fragmentation-based attack against legacy IPv6 nodes that do not implement [RFC6946]. That is, employing\n fragmentation where not actually needed allows for fragmentation-based attack vectors to be employed,\n unnecessarily. We note that, unfortunately, even nodes that already implement [RFC6946] can be subject to\n DoS attacks as a result of the generation of IPv6 atomic fragments. Let us assume that Host A is\n communicating with Host B and that, as a result of the widespread dropping of IPv6 packets that contain\n extension headers (including fragmentation) [RFC7872], some intermediate node filters fragments between\n Host B and Host A. If an attacker sends a forged ICMPv6 PTB error message to Host B, reporting an MTU\n smaller than 1280, this will trigger the generation of IPv6 atomic fragments from that moment on (as\n required by [RFC2460]). When Host B starts sending IPv6 atomic fragments (in response to the received\n ICMPv6 PTB error message), these packets will be dropped, since we previously noted that IPv6 packets with\n extension headers were being dropped between Host B and Host A. Thus, this situation will result in a DoS\n scenario. Another possible scenario is that in which two BGP peers are employing IPv6 transport and they\n implement Access Control Lists (ACLs) to drop IPv6 fragments (to avoid control-plane attacks). If the\n aforementioned BGP peers drop IPv6 fragments but still honor received ICMPv6 PTB error messages, an\n attacker could easily attack the corresponding peering session by simply sending an ICMPv6 PTB message\n with a reported MTU smaller than 1280 bytes. Once the attack packet has been sent, the aforementioned\n routers will themselves be the ones dropping their own traffic.

vulnerabilities :\n\n - An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions past bounds check. The flaw relies on the presence of a precisely-defined instruction sequence in the privileged code and the fact that memory writes occur to an address which depends on the untrusted value. Such writes cause an update into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). As a result, an unprivileged attacker could use this flaw to influence speculative execution and/or read privileged memory by conducting targeted cache side-channel attacks.(CVE-2018-3693)\n\n - A flaw named SegmentSmack was found in the way the Linux kernel handled specially crafted TCP packets. A remote attacker could use this flaw to trigger time and calculation expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() functions by sending specially modified packets within ongoing TCP sessions which could lead to a CPU saturation and hence a denial of service on the system. Maintaining the denial of service condition requires continuous two-way TCP sessions to a reachable open port, thus the attacks cannot be performed using spoofed IP addresses.(CVE-2018-5390)\n\n - It was found that the raw midi kernel driver does not protect against concurrent access which leads to a double realloc (double free) in snd_rawmidi_input_params() and snd_rawmidi_output_status() which are part of snd_rawmidi_ioctl() handler in rawmidi.c file. A malicious local attacker could possibly use this for privilege escalation.(CVE-2018-10902)\n\n - Integer overflow in the aio_setup_single_vector function in fs/aio.c in the Linux kernel 4.0 allows local users to cause a denial of service or possibly have unspecified other impact via a large AIO iovec.\n NOTE: this vulnerability exists because of a CVE-2012-6701 regression.(CVE-2015-8830)\n\n - A flaw was found in the Linux networking subsystem where a local attacker with CAP_NET_ADMIN capabilities could cause an out-of-bounds memory access by creating a smaller-than-expected ICMP header and sending to its destination via sendto().(CVE-2016-8399)\n\n - Out-of-bounds kernel heap access vulnerability was found in xfrm, kernel's IP framework for transforming packets. An error dealing with netlink messages from an unprivileged user leads to arbitrary read/write and privilege escalation.(CVE-2017-7184)\n\n - The Linux kernel was found to be vulnerable to a NULL pointer dereference bug in the __netlink_ns_capable() function in the net/netlink/af_netlink.c file. A local attacker could exploit this when a net namespace with a netnsid is assigned to cause a kernel panic and a denial of service.i1/4^CVE-2018-14646i1/4%0\n\n - A flaw was found where the kernel truncated the value used to indicate the size of a buffer which it would later become zero using an untruncated value. This can corrupt memory outside of the original allocation.(CVE-2017-9725)\n\n - A bug in the 32-bit compatibility layer of the ioctl handling code of the v4l2 video driver in the Linux kernel has been found. A memory protection mechanism ensuring that user-provided buffers always point to a userspace memory were disabled, allowing destination address to be in a kernel space. This flaw could be exploited by an attacker to overwrite a kernel memory from an unprivileged userspace process, leading to privilege escalation.(CVE-2017-13166)\n\n - An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions (a commonly used performance optimization). There are three primary variants of the issue which differ in the way the speculative execution can be exploited. Variant CVE-2017-5754 relies on the fact that, on impacted microprocessors, during speculative execution of instruction permission faults, exception generation triggered by a faulting access is suppressed until the retirement of the whole instruction block. In a combination with the fact that memory accesses may populate the cache even when the block is being dropped and never committed (executed), an unprivileged local attacker could use this flaw to read privileged (kernel space) memory by conducting targeted cache side-channel attacks. Note:\n CVE-2017-5754 affects Intel x86-64 microprocessors. AMD x86-64 microprocessors are not affected by this issue.(CVE-2017-5754)\n\n - An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions (a commonly used performance optimization). There are three primary variants of the issue which differ in the way the speculative execution can be exploited. Variant CVE-2017-5753 triggers the speculative execution by performing a bounds-check bypass. It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory accesses may cause allocation into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). As a result, an unprivileged attacker could use this flaw to cross the syscall boundary and read privileged memory by conducting targeted cache side-channel attacks.(CVE-2017-5753)\n\n - A flaw was found in the Linux kernel's skcipher component, which affects the skcipher_recvmsg function.\n Attackers using a specific input can lead to a privilege escalation.i1/4^CVE-2017-13215i1/4%0\n\n - The tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c in the Linux kernel before 4.11, and 4.9.x before 4.9.36, allows remote attackers to cause a denial of service (use-after-free and memory corruption) or possibly have unspecified other impact by leveraging the presence of xt_TCPMSS in an iptables action. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely.i1/4^CVE-2017-18017i1/4%0\n\n - A kernel data leak due to an out-of-bound read was found in the Linux kernel in inet_diag_msg_sctp{,l}addr_fill() and sctp_get_sctp_info() functions present since version 4.7-rc1 through version 4.13. A data leak happens when these functions fill in sockaddr data structures used to export socket's diagnostic information. As a result, up to 100 bytes of the slab data could be leaked to a userspace.i1/4^CVE-2017-7558i1/4%0\n\n - Use-after-free vulnerability in the snd_pcm_info() function in the ALSA subsystem in the Linux kernel allows attackers to induce a kernel memory corruption and possibly crash or lock up a system. Due to the nature of the flaw, a privilege escalation cannot be fully ruled out, although we believe it is unlikely.i1/4^CVE-2017-0861i1/4%0\n\n - Improper validation in the bnx2x network card driver of the Linux kernel version 4.15 can allow for denial of service (DoS) attacks via a packet with a gso_size larger than ~9700 bytes. Untrusted guest VMs can exploit this vulnerability in the host machine, causing a crash in the network card.i1/4^CVE-2018-1000026i1/4%0\n\n - An error in the '_sctp_make_chunk()' function (net/sctp/sm_make_chunk.c) when handling SCTP, packet length can be exploited by a malicious local user to cause a kernel crash and a DoS.i1/4^CVE-2018-5803i1/4%0\n\nNote that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory.

The flaw\n relies on the presence of a precisely-defined\n instruction sequence in the privileged code and the\n fact that memory writes occur to an address which\n depends on the untrusted value. Such writes cause an\n update into the microprocessor's data cache even for\n speculatively executed instructions that never actually\n commit (retire). As a result, an unprivileged attacker\n could use this flaw to influence speculative execution\n and/or read privileged memory by conducting targeted\n cache side-channel attacks.(CVE-2018-3693)\n\n - A flaw named SegmentSmack was found in the way the\n Linux kernel handled specially crafted TCP packets. A\n remote attacker could use this flaw to trigger time and\n calculation expensive calls to tcp_collapse_ofo_queue()\n and tcp_prune_ofo_queue() functions by sending\n specially modified packets within ongoing TCP sessions\n which could lead to a CPU saturation and hence a denial\n of service on the system. Maintaining the denial of\n service condition requires continuous two-way TCP\n sessions to a reachable open port, thus the attacks\n cannot be performed using spoofed IP\n addresses.(CVE-2018-5390)\n\n - It was found that the raw midi kernel driver does not\n protect against concurrent access which leads to a\n double realloc (double free) in\n snd_rawmidi_input_params() and\n snd_rawmidi_output_status() which are part of\n snd_rawmidi_ioctl() handler in rawmidi.c file. A\n malicious local attacker could possibly use this for\n privilege escalation.(CVE-2018-10902)\n\n - Integer overflow in the aio_setup_single_vector\n function in fs/aio.c in the Linux kernel 4.0 allows\n local users to cause a denial of service or possibly\n have unspecified other impact via a large AIO iovec.\n NOTE: this vulnerability exists because of a\n CVE-2012-6701 regression.(CVE-2015-8830)\n\n - A flaw was found in the Linux networking subsystem\n where a local attacker with CAP_NET_ADMIN capabilities\n could cause an out-of-bounds memory access by creating\n a smaller-than-expected ICMP header and sending to its\n destination via sendto().(CVE-2016-8399)\n\n - Out-of-bounds kernel heap access vulnerability was\n found in xfrm, kernel's IP framework for transforming\n packets. An error dealing with netlink messages from an\n unprivileged user leads to arbitrary read/write and\n privilege escalation.(CVE-2017-7184)\n\n - The Linux kernel was found to be vulnerable to a NULL\n pointer dereference bug in the __netlink_ns_capable()\n function in the net/netlink/af_netlink.c file. A local\n attacker could exploit this when a net namespace with a\n netnsid is assigned to cause a kernel panic and a\n denial of service.i1/4^CVE-2018-14646i1/4%0\n\n - A flaw was found where the kernel truncated the value\n used to indicate the size of a buffer which it would\n later become zero using an untruncated value. This can\n corrupt memory outside of the original\n allocation.(CVE-2017-9725)\n\n - A bug in the 32-bit compatibility layer of the ioctl\n handling code of the v4l2 video driver in the Linux\n kernel has been found. A memory protection mechanism\n ensuring that user-provided buffers always point to a\n userspace memory were disabled, allowing destination\n address to be in a kernel space. This flaw could be\n exploited by an attacker to overwrite a kernel memory\n from an unprivileged userspace process, leading to\n privilege escalation.(CVE-2017-13166)\n\n - An industry-wide issue was found in the way many modern\n microprocessor designs have implemented speculative\n execution of instructions (a commonly used performance\n optimization). There are three primary variants of the\n issue which differ in the way the speculative execution\n can be exploited. Variant CVE-2017-5754 relies on the\n fact that, on impacted microprocessors, during\n speculative execution of instruction permission faults,\n exception generation triggered by a faulting access is\n suppressed until the retirement of the whole\n instruction block. In a combination with the fact that\n memory accesses may populate the cache even when the\n block is being dropped and never committed (executed),\n an unprivileged local attacker could use this flaw to\n read privileged (kernel space) memory by conducting\n targeted cache side-channel attacks. Note:\n CVE-2017-5754 affects Intel x86-64 microprocessors. AMD\n x86-64 microprocessors are not affected by this\n issue.(CVE-2017-5754)\n\n - An industry-wide issue was found in the way many modern\n microprocessor designs have implemented speculative\n execution of instructions (a commonly used performance\n optimization).

security impact. Additionally, in kernel versions prior to 3.5, any user could do this if sysctl net.core.rmem_max was changed to a very large value.\n\nCVE-2015-1350 / #770492\n\nBen Harris reported that local users could remove set-capability attributes from any file visible to them, allowing a denial of service.\n\nCVE-2015-8962\n\nCalvin Owens fouund that removing a SCSI device while it was being accessed through the SCSI generic (sg) driver led to a double- free, possibly causing a denial of service (crash or memory corruption) or privilege escalation. This could be exploited by local users with permision to access a SCSI device node.\n\nCVE-2015-8963\n\nSasha Levin reported that hot-unplugging a CPU resulted in a use-after-free by the performance events (perf) subsystem, possibly causing a denial of service (crash or memory corruption) or privilege escalation. This could by exploited by any local user.\n\nCVE-2015-8964\n\nIt was found that the terminal/serial (tty) subsystem did not reliably reset the terminal buffer state when the terminal line discipline was changed. This could allow a local user with access to a terminal device to read sensitive information from kernel memory.\n\nCVE-2016-7097\n\nJan Kara found that changing the POSIX ACL of a file never cleared its set-group-ID flag, which should be done if the user changing it is not a member of the group-owner. In some cases, this would allow the user-owner of an executable to gain the privileges of the group-owner.\n\nCVE-2016-7910\n\nVegard Nossum discovered that a memory allocation failure while handling a read of /proc/diskstats or /proc/partitions could lead to a use-after-free, possibly causing a denial of service (crash or memory corruption) or privilege escalation.\n\nCVE-2016-7911\n\nDmitry Vyukov reported that a race between ioprio_get() and ioprio_set() system calls could result in a use-after-free, possibly causing a denial of service (crash) or leaking sensitive information.\n\nCVE-2016-7915\n\nBenjamin Tissoires found that HID devices could trigger an out-of- bounds memory access in the HID core.

Local users with access to a PCM sound device could exploit this for denial of service (crash or memory corruption) or other security impact.\n\nFor Debian 7 'Wheezy', these problems have been fixed in version 3.2.84-1. This version also includes bug fixes from upstream version 3.2.84 and updates the PREEMPT_RT featureset to version 3.2.84-rt122.\nFinally, this version adds the option to mitigate security issues in the performance events (perf) subsystem by disabling use by unprivileged users. This can be done by setting sysctl kernel.perf_event_paranoid=3.\n\nFor Debian 8 'Jessie', these problems have been fixed in version 3.16.39-1 which will be included in the next point release (8.6).\n\nWe recommend that you upgrade your linux packages.\n\nNOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory.

Local users with access to a\nPCM sound device could exploit this for denial of service (crash or\nmemory corruption) or other security impact.\n\nFor Debian 7 'Wheezy', these problems have been fixed in version\n3.2.84-1. This version also includes bug fixes from upstream version\n3.2.84 and updates the PREEMPT_RT featureset to version 3.2.84-rt122.\nFinally, this version adds the option to mitigate security issues in\nthe performance events (perf) subsystem by disabling use by\nunprivileged users. This can be done by setting sysctl\nkernel.perf_event_paranoid=3.\n\nFor Debian 8 'Jessie', these problems have been fixed in version\n3.16.39-1 which will be included in the next point release (8.6).\n\nWe recommend that you upgrade your linux packages.\n\nNOTE: Tenable Network Security has extracted the preceding description\nblock directly from the DLA security advisory.

The following security bugs were fixed :\n\n - CVE-2017-5551: tmpfs: clear S_ISGID when setting posix ACLs (bsc#1021258).\n\n - CVE-2016-10088: The sg implementation in the Linux kernel did not properly restrict write operations in situations where the KERNEL_DS option is set, which allowed local users to read or write to arbitrary kernel memory locations or cause a denial of service (use-after-free) by leveraging access to a /dev/sg device NOTE: this vulnerability existed because of an incomplete fix for CVE-2016-9576 (bnc#1017710).\n\n - CVE-2016-5696: TCP, when using a large Window Size, made it easier for remote attackers to guess sequence numbers and cause a denial of service (connection loss) to persistent TCP connections by repeatedly injecting a TCP RST packet, especially in protocols that use long-lived connections, such as BGP (bnc#989152).\n\n - CVE-2015-1350: The VFS subsystem in the Linux kernel 3.x provided an incomplete set of requirements for setattr operations that underspecified removing extended privilege attributes, which allowed local users to cause a denial of service (capability stripping) via a failed invocation of a system call, as demonstrated by using chown to remove a capability from the ping or Wireshark dumpcap program (bnc#914939).\n\n - CVE-2016-8632: The tipc_msg_build function in net/tipc/msg.c in the Linux kernel did not validate the relationship between the minimum fragment length and the maximum packet size, which allowed local users to gain privileges or cause a denial of service (heap-based buffer overflow) by leveraging the CAP_NET_ADMIN capability (bnc#1008831).\n\n - CVE-2016-8399: An elevation of privilege vulnerability in the kernel networking subsystem could enable a local malicious application to execute arbitrary code within the context of the kernel. This issue is rated as Moderate because it first requires compromising a privileged process and current compiler optimizations restrict access to the vulnerable code. (bnc#1014746).\n\n - CVE-2016-9793: The sock_setsockopt function in net/core/sock.c in the Linux kernel mishandled negative values of sk_sndbuf and sk_rcvbuf, which allowed local users to cause a denial of service (memory corruption and system crash) or possibly have unspecified other impact by leveraging the CAP_NET_ADMIN capability for a crafted setsockopt system call with the (1) SO_SNDBUFFORCE or (2) SO_RCVBUFFORCE option (bnc#1013531).\n\n - CVE-2012-6704: The sock_setsockopt function in net/core/sock.c in the Linux kernel mishandled negative values of sk_sndbuf and sk_rcvbuf, which allowed local users to cause a denial of service (memory corruption and system crash) or possibly have unspecified other impact by leveraging the CAP_NET_ADMIN capability for a crafted setsockopt system call with the (1) SO_SNDBUF or (2) SO_RCVBUF option (bnc#1013542).\n\n - CVE-2016-9756: arch/x86/kvm/emulate.c in the Linux kernel did not properly initialize Code Segment (CS) in certain error cases, which allowed local users to obtain sensitive information from kernel stack memory via a crafted application (bnc#1013038).\n\n - CVE-2016-9685: Multiple memory leaks in error paths in fs/xfs/xfs_attr_list.c in the Linux kernel allowed local users to cause a denial of service (memory consumption) via crafted XFS filesystem operations (bnc#1012832).\n\n - CVE-2015-8962: Double free vulnerability in the sg_common_write function in drivers/scsi/sg.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (memory corruption and system crash) by detaching a device during an SG_IO ioctl call (bnc#1010501).\n\n - CVE-2016-9555: The sctp_sf_ootb function in net/sctp/sm_statefuns.c in the Linux kernel lacked chunk-length checking for the first chunk, which allowed remote attackers to cause a denial of service (out-of-bounds slab access) or possibly have unspecified other impact via crafted SCTP data (bnc#1011685).\n\n - CVE-2016-7910: Use-after-free vulnerability in the disk_seqf_stop function in block/genhd.c in the Linux kernel allowed local users to gain privileges by leveraging the execution of a certain stop operation even if the corresponding start operation had failed (bnc#1010716).\n\n - CVE-2016-7911: Race condition in the get_task_ioprio function in block/ioprio.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (use-after-free) via a crafted ioprio_get system call (bnc#1010711).\n\n - CVE-2013-6368: The KVM subsystem in the Linux kernel allowed local users to gain privileges or cause a denial of service (system crash) via a VAPIC synchronization operation involving a page-end address (bnc#853052).\n\n - CVE-2015-8964: The tty_set_termios_ldisc function in drivers/tty/tty_ldisc.c in the Linux kernel allowed local users to obtain sensitive information from kernel memory by reading a tty data structure (bnc#1010507).\n\n - CVE-2016-7916: Race condition in the environ_read function in fs/proc/base.c in the Linux kernel allowed local users to obtain sensitive information from kernel memory by reading a /proc/*/environ file during a process-setup time interval in which environment-variable copying is incomplete (bnc#1010467).\n\n - CVE-2016-8646: The hash_accept function in crypto/algif_hash.c in the Linux kernel allowed local users to cause a denial of service (OOPS) by attempting to trigger use of in-kernel hash algorithms for a socket that has received zero bytes of data (bnc#1010150).\n\n - CVE-2016-8633: drivers/firewire/net.c in the Linux kernel, in certain unusual hardware configurations, allowed remote attackers to execute arbitrary code via crafted fragmented packets (bnc#1008833).\n\nThe update package also includes non-security fixes.

A use-after-free vulnerability was found in the kernel's socket recvmmsg subsystem. This may allow remote attackers to corrupt memory and may allow execution of arbitrary code. This corruption takes place during the error handling routines within\n __sys_recvmmsg() function.(CVE-2016-7117)\n\n - A heap-buffer overflow vulnerability was found in the arcmsr_iop_message_xfer() function in 'drivers/scsi/arcmsr/arcmsr_hba.c' file in the Linux kernel through 4.8.2. The function does not restrict a certain length field, which allows local users to gain privileges or cause a denial of service via an ARCMSR_MESSAGE_WRITE_WQBUFFER control code. This can potentially cause kernel heap corruption and arbitrary kernel code execution.(CVE-2016-7425)\n\n - A flaw was found in the Linux kernel's implementation of seq_file where a local attacker could manipulate memory in the put() function pointer. This could lead to memory corruption and possible privileged escalation.(CVE-2016-7910)\n\n - A use-after-free vulnerability in sys_ioprio_get() was found due to get_task_ioprio() accessing the task-i1/4zio_context without holding the task lock and could potentially race with exit_io_context(), leading to a use-after-free.(CVE-2016-7911)\n\n - The xc2028_set_config function in drivers/media/tuners/tuner-xc2028.c in the Linux kernel before 4.6 allows local users to gain privileges or cause a denial of service (use-after-free) via vectors involving omission of the firmware name from a certain data structure. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely.(CVE-2016-7913)\n\n - The assoc_array_insert_into_terminal_node() function in 'lib/assoc_array.c' in the Linux kernel before 4.5.3 does not check whether a slot is a leaf, which allows local users to obtain sensitive information from kernel memory or cause a denial of service (invalid pointer dereference and out-of-bounds read) via an application that uses associative-array data structures.(CVE-2016-7914)\n\n - The hid_input_field() function in 'drivers/hid/hid-core.c' in the Linux kernel before 4.6 allows physically proximate attackers to obtain sensitive information from kernel memory or cause a denial of service (out-of-bounds read) by connecting a device.(CVE-2016-7915)\n\n - Race condition in the environ_read() function in 'fs/proc/base.c' in the Linux kernel before 4.5.4 allows local users to obtain sensitive information from kernel memory by reading a '/proc/*/environ' file during a process-setup time interval in which environment-variable copying is incomplete.(CVE-2016-7916)\n\n - A flaw was found in the Linux networking subsystem where a local attacker with CAP_NET_ADMIN capabilities could cause an out-of-bounds memory access by creating a smaller-than-expected ICMP header and sending to its destination via sendto().(CVE-2016-8399)\n\n - Linux kernel built with the Kernel-based Virtual Machine (CONFIG_KVM) support is vulnerable to a null pointer dereference flaw. It could occur on x86 platform, when emulating an undefined instruction. An attacker could use this flaw to crash the host kernel resulting in DoS.(CVE-2016-8630)\n\n - A buffer overflow vulnerability due to a lack of input filtering of incoming fragmented datagrams was found in the IP-over-1394 driver firewire-net in a fragment handling code in the Linux kernel. The vulnerability exists since firewire supported IPv4, i.e. since version 2.6.31 (year 2009) till version v4.9-rc4. A maliciously formed fragment with a respectively large datagram offset would cause a memcpy() past the datagram buffer, which would cause a system panic or possible arbitrary code execution.The flaw requires firewire-net module to be loaded and is remotely exploitable from connected firewire devices, but not over a local network.(CVE-2016-8633)\n\n - It was discovered that the Linux kernel since 3.6-rc1 with 'net.ipv4.tcp_fastopen' set to 1 can hit BUG() statement in tcp_collapse() function after making a number of certain syscalls leading to a possible system crash.(CVE-2016-8645)\n\n - A vulnerability was found in the Linux kernel. An unprivileged local user could trigger oops in shash_async_export() by attempting to force the in-kernel hashing algorithms into decrypting an empty data set.(CVE-2016-8646)\n\n - A flaw was found in the Linux kernel key management subsystem in which a local attacker could crash the kernel or corrupt the stack and additional memory (denial of service) by supplying a specially crafted RSA key. This flaw panics the machine during the verification of the RSA key.(CVE-2016-8650)\n\n - A race condition issue leading to a use-after-free flaw was found in the way the raw packet sockets implementation in the Linux kernel networking subsystem handled synchronization while creating the TPACKET_V3 ring buffer. A local user able to open a raw packet socket (requires the CAP_NET_RAW capability) could use this flaw to elevate their privileges on the system.(CVE-2016-8655)\n\n - A flaw was found in the way the Linux kernel's networking subsystem handled offloaded packets with multiple layers of encapsulation in the GRO (Generic Receive Offload) code path. A remote attacker could use this flaw to trigger unbounded recursion in the kernel that could lead to stack corruption, resulting in a system crash.(CVE-2016-8666)\n\n - A flaw was discovered in the Linux kernel's implementation of VFIO. An attacker issuing an ioctl can create a situation where memory is corrupted and modify memory outside of the expected area. This may overwrite kernel memory and subvert kernel execution.(CVE-2016-9083)\n\n - The use of a kzalloc with an integer multiplication allowed an integer overflow condition to be reached in vfio_pci_intrs.c. This combined with CVE-2016-9083 may allow an attacker to craft an attack and use unallocated memory, potentially crashing the machine.(CVE-2016-9084)\n\n - A flaw was found in the Linux kernel's implementation of the SCTP protocol. A remote attacker could trigger an out-of-bounds read with an offset of up to 64kB potentially causing the system to crash.(CVE-2016-9555)\n\n - It was found that the blk_rq_map_user_iov() function in the Linux kernel's block device implementation did not properly restrict the type of iterator, which could allow a local attacker to read or write to arbitrary kernel memory locations or cause a denial of service (use-after-free) by leveraging write access to a /dev/sg device.(CVE-2016-9576)\n\n - Linux kernel built with the KVM visualization support (CONFIG_KVM), with nested visualization(nVMX) feature enabled(nested=1), is vulnerable to an uncaught exception issue. It could occur if an L2 guest was to throw an exception which is not handled by an L1 guest.(CVE-2016-9588)\n\n - It was discovered that root can gain direct access to an internal keyring, such as '.dns_resolver' in RHEL-7 or '.builtin_trusted_keys' upstream, by joining it as its session keyring.

This may allow\n remote attackers to corrupt memory and may allow\n execution of arbitrary code. This corruption takes\n place during the error handling routines within\n __sys_recvmmsg() function.(CVE-2016-7117)\n\n - A heap-buffer overflow vulnerability was found in the\n arcmsr_iop_message_xfer() function in\n 'drivers/scsi/arcmsr/arcmsr_hba.c' file in the Linux\n kernel through 4.8.2. The function does not restrict a\n certain length field, which allows local users to gain\n privileges or cause a denial of service via an\n ARCMSR_MESSAGE_WRITE_WQBUFFER control code. This can\n potentially cause kernel heap corruption and arbitrary\n kernel code execution.(CVE-2016-7425)\n\n - A flaw was found in the Linux kernel's implementation\n of seq_file where a local attacker could manipulate\n memory in the put() function pointer. This could lead\n to memory corruption and possible privileged\n escalation.(CVE-2016-7910)\n\n - A use-after-free vulnerability in sys_ioprio_get() was\n found due to get_task_ioprio() accessing the\n task-i1/4zio_context without holding the task lock and\n could potentially race with exit_io_context(), leading\n to a use-after-free.(CVE-2016-7911)\n\n - The xc2028_set_config function in\n drivers/media/tuners/tuner-xc2028.c in the Linux kernel\n before 4.6 allows local users to gain privileges or\n cause a denial of service (use-after-free) via vectors\n involving omission of the firmware name from a certain\n data structure. Due to the nature of the flaw,\n privilege escalation cannot be fully ruled out,\n although we believe it is unlikely.(CVE-2016-7913)\n\n - The assoc_array_insert_into_terminal_node() function in\n 'lib/assoc_array.c' in the Linux kernel before 4.5.3\n does not check whether a slot is a leaf, which allows\n local users to obtain sensitive information from kernel\n memory or cause a denial of service (invalid pointer\n dereference and out-of-bounds read) via an application\n that uses associative-array data\n structures.(CVE-2016-7914)\n\n - The hid_input_field() function in\n 'drivers/hid/hid-core.c' in the Linux kernel before 4.6\n allows physically proximate attackers to obtain\n sensitive information from kernel memory or cause a\n denial of service (out-of-bounds read) by connecting a\n device.(CVE-2016-7915)\n\n - Race condition in the environ_read() function in\n 'fs/proc/base.c' in the Linux kernel before 4.5.4\n allows local users to obtain sensitive information from\n kernel memory by reading a '/proc/*/environ' file\n during a process-setup time interval in which\n environment-variable copying is\n incomplete.(CVE-2016-7916)\n\n - A flaw was found in the Linux networking subsystem\n where a local attacker with CAP_NET_ADMIN capabilities\n could cause an out-of-bounds memory access by creating\n a smaller-than-expected ICMP header and sending to its\n destination via sendto().(CVE-2016-8399)\n\n - Linux kernel built with the Kernel-based Virtual\n Machine (CONFIG_KVM) support is vulnerable to a null\n pointer dereference flaw.

An\n attacker could use this flaw to crash the host kernel\n resulting in DoS.(CVE-2016-8630)\n\n - A buffer overflow vulnerability due to a lack of input\n filtering of incoming fragmented datagrams was found in\n the IP-over-1394 driver firewire-net in a fragment\n handling code in the Linux kernel. The vulnerability\n exists since firewire supported IPv4, i.e. since\n version 2.6.31 (year 2009) till version v4.9-rc4. A\n maliciously formed fragment with a respectively large\n datagram offset would cause a memcpy() past the\n datagram buffer, which would cause a system panic or\n possible arbitrary code execution.The flaw requires\n firewire-net module to be loaded and is remotely\n exploitable from connected firewire devices, but not\n over a local network.(CVE-2016-8633)\n\n - It was discovered that the Linux kernel since 3.6-rc1\n with 'net.ipv4.tcp_fastopen' set to 1 can hit BUG()\n statement in tcp_collapse() function after making a\n number of certain syscalls leading to a possible system\n crash.(CVE-2016-8645)\n\n - A vulnerability was found in the Linux kernel. An\n unprivileged local user could trigger oops in\n shash_async_export() by attempting to force the\n in-kernel hashing algorithms into decrypting an empty\n data set.(CVE-2016-8646)\n\n - A flaw was found in the Linux kernel key management\n subsystem in which a local attacker could crash the\n kernel or corrupt the stack and additional memory\n (denial of service) by supplying a specially crafted\n RSA key. This flaw panics the machine during the\n verification of the RSA key.(CVE-2016-8650)\n\n - A race condition issue leading to a use-after-free flaw\n was found in the way the raw packet sockets\n implementation in the Linux kernel networking subsystem\n handled synchronization while creating the TPACKET_V3\n ring buffer. A local user able to open a raw packet\n socket (requires the CAP_NET_RAW capability) could use\n this flaw to elevate their privileges on the\n system.(CVE-2016-8655)\n\n - A flaw was found in the way the Linux kernel's\n networking subsystem handled offloaded packets with\n multiple layers of encapsulation in the GRO (Generic\n Receive Offload) code path. A remote attacker could use\n this flaw to trigger unbounded recursion in the kernel\n that could lead to stack corruption, resulting in a\n system crash.(CVE-2016-8666)\n\n - A flaw was discovered in the Linux kernel's\n implementation of VFIO. An attacker issuing an ioctl\n can create a situation where memory is corrupted and\n modify memory outside of the expected area. This may\n overwrite kernel memory and subvert kernel\n execution.(CVE-2016-9083)\n\n - The use of a kzalloc with an integer multiplication\n allowed an integer overflow condition to be reached in\n vfio_pci_intrs.c. This combined with CVE-2016-9083 may\n allow an attacker to craft an attack and use\n unallocated memory, potentially crashing the\n machine.(CVE-2016-9084)\n\n - A flaw was found in the Linux kernel's implementation\n of the SCTP protocol. A remote attacker could trigger\n an out-of-bounds read with an offset of up to 64kB\n potentially causing the system to crash.(CVE-2016-9555)\n\n - It was found that the blk_rq_map_user_iov() function in\n the Linux kernel's block device implementation did not\n properly restrict the type of iterator, which could\n allow a local attacker to read or write to arbitrary\n kernel memory locations or cause a denial of service\n (use-after-free) by leveraging write access to a\n /dev/sg device.(CVE-2016-9576)\n\n - Linux kernel built with the KVM visualization support\n (CONFIG_KVM), with nested visualization(nVMX) feature\n enabled(nested=1), is vulnerable to an uncaught\n exception issue. It could occur if an L2 guest was to\n throw an exception which is not handled by an L1\n guest.(CVE-2016-9588)\n\n - It was discovered that root can gain direct access to\n an internal keyring, such as '.dns_resolver' in RHEL-7\n or '.builtin_trusted_keys' upstream, by joining it as\n its session keyring. This allows root to bypass module\n signature verification by adding a new public key of\n its own devising to the keyring.(CVE-2016-9604)\n\n - A flaw was found in the Linux kernel's implementation\n of XFS file attributes. Two memory leaks were detected\n in xfs_attr_shortform_list and xfs_attr3_leaf_list_int\n when running a docker container backed by xfs/overlay2.\n A dedicated attacker could possible exhaust all memory\n and create a denial of service\n situation.(CVE-2016-9685)\n\nNote that Tenable Network Security has extracted the preceding\ndescription block directly from the EulerOS security advisory.

(CVE-2016-8399)\n\n - An issue was discovered in the IPv6 protocol specification, related to ICMP Packet Too Big (PTB) messages.\n (The scope of this CVE is all affected IPv6 implementations from all vendors.) The security implications of IP fragmentation have been discussed at length in [RFC6274] and [RFC7739]. An attacker can leverage the generation of IPv6 atomic fragments to trigger the use of fragmentation in an arbitrary IPv6 flow (in scenarios in which actual fragmentation of packets is not needed) and can subsequently perform any type of fragmentation-based attack against legacy IPv6 nodes that do not implement [RFC6946]. That is, employing fragmentation where not actually needed allows for fragmentation-based attack vectors to be employed, unnecessarily. We note that, unfortunately, even nodes that already implement [RFC6946] can be subject to DoS attacks as a result of the generation of IPv6 atomic fragments. Let us assume that Host A is communicating with Host B and that, as a result of the widespread dropping of IPv6 packets that contain extension headers (including fragmentation) [RFC7872], some intermediate node filters fragments between Host B and Host A. If an attacker sends a forged ICMPv6 PTB error message to Host B, reporting an MTU smaller than 1280, this will trigger the generation of IPv6 atomic fragments from that moment on (as required by [RFC2460]). When Host B starts sending IPv6 atomic fragments (in response to the received ICMPv6 PTB error message), these packets will be dropped, since we previously noted that IPv6 packets with extension headers were being dropped between Host B and Host A. Thus, this situation will result in a DoS scenario. Another possible scenario is that in which two BGP peers are employing IPv6 transport and they implement Access Control Lists (ACLs) to drop IPv6 fragments (to avoid control-plane attacks). If the aforementioned BGP peers drop IPv6 fragments but still honor received ICMPv6 PTB error messages, an attacker could easily attack the corresponding peering session by simply sending an ICMPv6 PTB message with a reported MTU smaller than 1280 bytes. Once the attack packet has been sent, the aforementioned routers will themselves be the ones dropping their own traffic.

(CVE-2016-8399)\n\n - An issue was discovered in the IPv6 protocol specification, related to ICMP Packet Too Big (PTB) messages.\n (The scope of this CVE is all affected IPv6 implementations from all vendors.) The security implications\n of IP fragmentation have been discussed at length in [RFC6274] and [RFC7739]. An attacker can leverage the\n generation of IPv6 atomic fragments to trigger the use of fragmentation in an arbitrary IPv6 flow (in\n scenarios in which actual fragmentation of packets is not needed) and can subsequently perform any type of\n fragmentation-based attack against legacy IPv6 nodes that do not implement [RFC6946]. That is, employing\n fragmentation where not actually needed allows for fragmentation-based attack vectors to be employed,\n unnecessarily. We note that, unfortunately, even nodes that already implement [RFC6946] can be subject to\n DoS attacks as a result of the generation of IPv6 atomic fragments. Let us assume that Host A is\n communicating with Host B and that, as a result of the widespread dropping of IPv6 packets that contain\n extension headers (including fragmentation) [RFC7872], some intermediate node filters fragments between\n Host B and Host A. If an attacker sends a forged ICMPv6 PTB error message to Host B, reporting an MTU\n smaller than 1280, this will trigger the generation of IPv6 atomic fragments from that moment on (as\n required by [RFC2460]). When Host B starts sending IPv6 atomic fragments (in response to the received\n ICMPv6 PTB error message), these packets will be dropped, since we previously noted that IPv6 packets with\n extension headers were being dropped between Host B and Host A.

CVE-2015-1350: The VFS subsystem in the Linux kernel provided an incomplete set of requirements for setattr operations that underspecifies removing extended privilege attributes, which allowed local users to cause a denial of service (capability stripping) via a failed invocation of a system call, as demonstrated by using chown to remove a capability from the ping or Wireshark dumpcap program (bnc#914939).\n\n - CVE-2015-8962: Double free vulnerability in the sg_common_write function in drivers/scsi/sg.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (memory corruption and system crash) by detaching a device during an SG_IO ioctl call (bnc#1010501).\n\n - CVE-2016-9555: The sctp_sf_ootb function in net/sctp/sm_statefuns.c in the Linux kernel lacked chunk-length checking for the first chunk, which allowed remote attackers to cause a denial of service (out-of-bounds slab access) or possibly have unspecified other impact via crafted SCTP data (bnc#1011685).\n\n - CVE-2016-7910: Use-after-free vulnerability in the disk_seqf_stop function in block/genhd.c in the Linux kernel allowed local users to gain privileges by leveraging the execution of a certain stop operation even if the corresponding start operation had failed (bnc#1010716).\n\n -

See advisory for\ndetails.\n\nNote that Tenable Network Security has extracted the preceding\ndescription block directly from the SUSE security advisory. Tenable\nhas attempted to automatically clean and format it as much as possible\nwithout introducing additional issues.\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n

The __rds_conn_create function in net/rds/connection.c in the Linux kernel through 4.2.3 allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by using a socket that was not properly bound. (CVE-2015-6937)\n\n - The load_segment_descriptor implementation in arch/x86/kvm/emulate.c in the Linux kernel before 4.9.5 improperly emulates a MOV SS, NULL selector instruction, which allows guest OS users to cause a denial of service (guest OS crash) or gain guest OS privileges via a crafted application. (CVE-2017-2583)\n\n - The tcp_splice_read function in net/ipv4/tcp.c in the Linux kernel before 4.9.11 allows remote attackers to cause a denial of service (infinite loop and soft lockup) via vectors involving a TCP packet with the URG flag. (CVE-2017-6214)\n\n - The xfrm_replay_verify_len function in net/xfrm/xfrm_user.c in the Linux kernel through 4.10.6 does not validate certain size data after an XFRM_MSG_NEWAE update, which allows local users to obtain root privileges or cause a denial of service (heap-based out-of-bounds access) by leveraging the CAP_NET_ADMIN capability, as demonstrated during a Pwn2Own competition at CanSecWest 2017 for the Ubuntu 16.10 linux- image-* package 4.8.0.41.52. (CVE-2017-7184)\n\n - Race condition in the sctp_wait_for_sndbuf function in net/sctp/socket.c in the Linux kernel before 4.9.11 allows local users to cause a denial of service (assertion failure and panic) via a multithreaded application that peels off an association in a certain buffer-full state. (CVE-2017-5986)\n\n - The NFSv2 and NFSv3 server implementations in the Linux kernel through 4.10.13 lack certain checks for the end of a buffer, which allows remote attackers to trigger pointer-arithmetic errors or possibly have unspecified other impact via crafted requests, related to fs/nfsd/nfs3xdr.c and fs/nfsd/nfsxdr.c.\n (CVE-2017-7895)\n\n - The vhost_dev_ioctl function in drivers/vhost/vhost.c in the Linux kernel before 4.1.5 allows local users to cause a denial of service (memory consumption) via a VHOST_SET_LOG_FD ioctl call that triggers permanent file-descriptor allocation. (CVE-2015-6252)\n\n - The KEYS subsystem in the Linux kernel before 3.18 allows local users to gain privileges or cause a denial of service (NULL pointer dereference and system crash) via vectors involving a NULL value for a certain match field, related to the keyring_search_iterator function in keyring.c. (CVE-2017-2647)\n\n - drivers/usb/serial/whiteheat.c in the Linux kernel before 4.2.4 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and OOPS) or possibly have unspecified other impact via a crafted USB device. NOTE: this ID was incorrectly used for an Apache Cordova issue that has the correct ID of CVE-2015-8320. (CVE-2015-5257)\n\n - The treo_attach function in drivers/usb/serial/visor.c in the Linux kernel before 4.5 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by inserting a USB device that lacks a (1) bulk-in or (2) interrupt-in endpoint. (CVE-2016-2782)\n\n - The do_shmat function in ipc/shm.c in the Linux kernel through 4.9.12 does not restrict the address calculated by a certain rounding operation, which allows local users to map page zero, and consequently bypass a protection mechanism that exists for the mmap system call, by making crafted shmget and shmat system calls in a privileged context.

"cvss": {"score": 10.0, "vector": "AV:N/AC:L/Au:N/C:C/I:C/A:C"}}, {"lastseen": "2023-02-16T15:19:11", "description": "The remote NewStart CGSL host, running version MAIN 4.05, has kernel packages installed that are affected by multiple vulnerabilities:\n\n - It was found that AIO interface didn't use the proper rw_verify_area() helper function with extended functionality, for example, mandatory locking on the file. Also rw_verify_area() makes extended checks, for example, that the size of the access doesn't cause overflow of the provided offset limits. This integer overflow in fs/aio.c in the Linux kernel before 3.4.1 allows local users to cause a denial of service or possibly have unspecified other impact via a large AIO iovec. (CVE-2012-6701)\n\n - Integer overflow in the aio_setup_single_vector function in fs/aio.c in the Linux kernel 4.0 allows local users to cause a denial of service or possibly have unspecified other impact via a large AIO iovec. NOTE:\n this vulnerability exists because of a CVE-2012-6701 regression. (CVE-2015-8830)\n\n - It was discovered that a remote attacker could leverage the generation of IPv6 atomic fragments to trigger the use of fragmentation in an arbitrary IPv6 flow (in scenarios in which actual fragmentation of packets is not needed) and could subsequently perform any type of a fragmentation-based attack against legacy IPv6 nodes that do not implement RFC6946. (CVE-2016-10142)\n\n - A race condition flaw was found in the ioctl_send_fib() function in the Linux kernel's aacraid implementation. A local attacker could use this flaw to cause a denial of service (out-of-bounds access or system crash) by changing a certain size value. (CVE-2016-6480)\n\n - It was found that when the gcc stack protector was enabled, reading the /proc/keys file could cause a panic in the Linux kernel due to stack corruption. This happened because an incorrect buffer size was used to hold a 64-bit timeout value rendered as weeks.\n (CVE-2016-7042)\n\n - It was found that when file permissions were modified via chmod and the user modifying them was not in the owning group or capable of CAP_FSETID, the setgid bit would be cleared. Setting a POSIX ACL via setxattr sets the file permissions as well as the new ACL, but doesn't clear the setgid bit in a similar way. This could allow a local user to gain group privileges via certain setgid applications. (CVE-2016-7097)\n\n - A flaw was found in the Linux networking subsystem where a local attacker with CAP_NET_ADMIN capabilities could cause an out-of-bounds memory access by creating a smaller-than-expected ICMP header and sending to its destination via sendto(). (CVE-2016-8399)\n\n - A flaw was found in the Linux kernel key management subsystem in which a local attacker could crash the kernel or corrupt the stack and additional memory (denial of service) by supplying a specially crafted RSA key. This flaw panics the machine during the verification of the RSA key. (CVE-2016-8650)\n\n - Use-after-free vulnerability in the snd_pcm_info() function in the ALSA subsystem in the Linux kernel allows attackers to induce a kernel memory corruption and possibly crash or lock up a system. Due to the nature of the flaw, a privilege escalation cannot be fully ruled out, although we believe it is unlikely.\n (CVE-2017-0861)\n\n - A race condition issue was found in the way the raw packet socket implementation in the Linux kernel networking subsystem handled synchronization. A local user able to open a raw packet socket (requires the CAP_NET_RAW capability) could use this to waste resources in the kernel's ring buffer or possibly cause an out-of-bounds read on the heap leading to a system crash. (CVE-2017-1000111)\n\n - A use-after-free flaw was found in the Netlink functionality of the Linux kernel networking subsystem.\n Due to the insufficient cleanup in the mq_notify function, a local attacker could potentially use this flaw to escalate their privileges on the system.\n (CVE-2017-11176)\n\n - It was found that in the Linux kernel through v4.14-rc5, bio_map_user_iov() and bio_unmap_user() in 'block/bio.c' do unbalanced pages refcounting if IO vector has small consecutive buffers belonging to the same page.\n bio_add_pc_page() merges them into one, but the page reference is never dropped, causing a memory leak and possible system lockup due to out-of-memory condition.\n (CVE-2017-12190)\n\n - A divide-by-zero vulnerability was found in the\n __tcp_select_window function in the Linux kernel. This can result in a kernel panic causing a local denial of service. (CVE-2017-14106)\n\n - A non-privileged user is able to mount a fuse filesystem on RHEL 6 or 7 and crash a system if an application punches a hole in a file that does not end aligned to a page boundary. (CVE-2017-15121)\n\n - A use-after-free vulnerability was found when issuing an ioctl to a sound device. This could allow a user to exploit a race condition and create memory corruption or possibly privilege escalation. (CVE-2017-15265)\n\n - The Linux kernel, before version 4.14.3, is vulnerable to a denial of service in drivers/md/dm.c:dm_get_from_kobject() which can be caused by local users leveraging a race condition with\n __dm_destroy() during creation and removal of DM devices. Only privileged local users (with CAP_SYS_ADMIN capability) can directly perform the ioctl operations for dm device creation and removal and this would typically be outside the direct control of the unprivileged attacker. (CVE-2017-18203)\n\n - A race condition leading to a NULL pointer dereference was found in the Linux kernel's Link Layer Control implementation. A local attacker with access to ping sockets could use this flaw to crash the system.\n (CVE-2017-2671)\n\n - It was found that the original fix for CVE-2016-6786 was incomplete. There exist a race between two concurrent sys_perf_event_open() calls when both try and move the same pre-existing software group into a hardware context. (CVE-2017-6001)\n\n - A flaw was found in the Linux kernel's handling of packets with the URG flag. Applications using the splice() and tcp_splice_read() functionality could allow a remote attacker to force the kernel to enter a condition in which it could loop indefinitely.\n (CVE-2017-6214)\n\n - Kernel memory corruption due to a buffer overflow was found in brcmf_cfg80211_mgmt_tx() function in Linux kernels from v3.9-rc1 to v4.13-rc1. The vulnerability can be triggered by sending a crafted NL80211_CMD_FRAME packet via netlink. This flaw is unlikely to be triggered remotely as certain userspace code is needed for this. An unprivileged local user could use this flaw to induce kernel memory corruption on the system, leading to a crash. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although it is unlikely. (CVE-2017-7541)\n\n - An integer overflow vulnerability in ip6_find_1stfragopt() function was found. A local attacker that has privileges (of CAP_NET_RAW) to open raw socket can cause an infinite loop inside the ip6_find_1stfragopt() function. (CVE-2017-7542)\n\n - Incorrect error handling in the set_mempolicy() and mbind() compat syscalls in 'mm/mempolicy.c' in the Linux kernel allows local users to obtain sensitive information from uninitialized stack data by triggering failure of a certain bitmap operation. (CVE-2017-7616)\n\n - The mm subsystem in the Linux kernel through 4.10.10 does not properly enforce the CONFIG_STRICT_DEVMEM protection mechanism, which allows local users to read or write to kernel memory locations in the first megabyte (and bypass slab-allocation access restrictions) via an application that opens the /dev/mem file, related to arch/x86/mm/init.c and drivers/char/mem.c. (CVE-2017-7889)\n\n - The IPv6 fragmentation implementation in the Linux kernel does not consider that the nexthdr field may be associated with an invalid option, which allows local users to cause a denial of service (out-of-bounds read and BUG) or possibly have unspecified other impact via crafted socket and send system calls. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely. (CVE-2017-9074)\n\n - In the Linux kernel versions 4.12, 3.10, 2.6, and possibly earlier, a race condition vulnerability exists in the sound system allowing for a potential deadlock and memory corruption due to use-after-free condition and thus denial of service. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely. (CVE-2018-1000004)\n\n - A null pointer dereference in dccp_write_xmit() function in net/dccp/output.c in the Linux kernel allows a local user to cause a denial of service by a number of certain crafted system calls. (CVE-2018-1130)\n\n - Modern Intel microprocessors implement hardware-level micro-optimizations to improve the performance of writing data back to CPU caches. The write operation is split into STA (STore Address) and STD (STore Data) sub- operations. These sub-operations allow the processor to hand-off address generation logic into these sub- operations for optimized writes. Both of these sub- operations write to a shared distributed processor structure called the 'processor store buffer'. As a result, an unprivileged attacker could use this flaw to read private data resident within the CPU's processor store buffer. (CVE-2018-12126)\n\n - Microprocessors use a load port subcomponent to perform load operations from memory or IO. During a load operation, the load port receives data from the memory or IO subsystem and then provides the data to the CPU registers and operations in the CPUs pipelines. Stale load operations results are stored in the 'load port' table until overwritten by newer operations. Certain load-port operations triggered by an attacker can be used to reveal data about previous stale requests leaking data back to the attacker via a timing side- channel. (CVE-2018-12127)\n\n - A flaw was found in the implementation of the fill buffer, a mechanism used by modern CPUs when a cache- miss is made on L1 CPU cache. If an attacker can generate a load operation that would create a page fault, the execution will continue speculatively with incorrect data from the fill buffer while the data is fetched from higher level caches. This response time can be measured to infer data in the fill buffer.\n (CVE-2018-12130)\n\n - A vulnerability was found in the fs/inode.c:inode_init_owner() function logic of the LInux kernel that allows local users to create files with an unintended group ownership and with group execution and SGID permission bits set, in a scenario where a directory is SGID and belongs to a certain group and is writable by a user who is not a member of this group. This can lead to excessive permissions granted in case when they should not. (CVE-2018-13405)\n\n - A Floating Point Unit (FPU) state information leakage flaw was found in the way the Linux kernel saved and restored the FPU state during task switch. Linux kernels that follow the Lazy FPU Restore scheme are vulnerable to the FPU state information leakage issue. An unprivileged local attacker could use this flaw to read FPU state bits by conducting targeted cache side-channel attacks, similar to the Meltdown vulnerability disclosed earlier this year. (CVE-2018-3665)\n\n - An error in the _sctp_make_chunk() function (net/sctp/sm_make_chunk.c) when handling SCTP, packet length can be exploited by a malicious local user to cause a kernel crash and a DoS. (CVE-2018-5803)\n\n - ALSA sequencer core initializes the event pool on demand by invoking snd_seq_pool_init() when the first write happens and the pool is empty.

Also rw_verify_area() makes extended checks, for\n example, that the size of the access doesn't cause\n overflow of the provided offset limits. This integer\n overflow in fs/aio.c in the Linux kernel before 3.4.1\n allows local users to cause a denial of service or\n possibly have unspecified other impact via a large AIO\n iovec. (CVE-2012-6701)\n\n - Integer overflow in the aio_setup_single_vector function\n in fs/aio.c in the Linux kernel 4.0 allows local users\n to cause a denial of service or possibly have\n unspecified other impact via a large AIO iovec. NOTE:\n this vulnerability exists because of a CVE-2012-6701\n regression. (CVE-2015-8830)\n\n - It was discovered that a remote attacker could leverage\n the generation of IPv6 atomic fragments to trigger the\n use of fragmentation in an arbitrary IPv6 flow (in\n scenarios in which actual fragmentation of packets is\n not needed) and could subsequently perform any type of a\n fragmentation-based attack against legacy IPv6 nodes\n that do not implement RFC6946. (CVE-2016-10142)\n\n - A race condition flaw was found in the ioctl_send_fib()\n function in the Linux kernel's aacraid implementation. A\n local attacker could use this flaw to cause a denial of\n service (out-of-bounds access or system crash) by\n changing a certain size value. (CVE-2016-6480)\n\n - It was found that when the gcc stack protector was\n enabled, reading the /proc/keys file could cause a panic\n in the Linux kernel due to stack corruption. This\n happened because an incorrect buffer size was used to\n hold a 64-bit timeout value rendered as weeks.\n (CVE-2016-7042)\n\n - It was found that when file permissions were modified\n via chmod and the user modifying them was not in the\n owning group or capable of CAP_FSETID, the setgid bit\n would be cleared. Setting a POSIX ACL via setxattr sets\n the file permissions as well as the new ACL, but doesn't\n clear the setgid bit in a similar way. This could allow\n a local user to gain group privileges via certain setgid\n applications. (CVE-2016-7097)\n\n - A flaw was found in the Linux networking subsystem where\n a local attacker with CAP_NET_ADMIN capabilities could\n cause an out-of-bounds memory access by creating a\n smaller-than-expected ICMP header and sending to its\n destination via sendto(). (CVE-2016-8399)\n\n - A flaw was found in the Linux kernel key management\n subsystem in which a local attacker could crash the\n kernel or corrupt the stack and additional memory\n (denial of service) by supplying a specially crafted RSA\n key. This flaw panics the machine during the\n verification of the RSA key. (CVE-2016-8650)\n\n - Use-after-free vulnerability in the snd_pcm_info()\n function in the ALSA subsystem in the Linux kernel\n allows attackers to induce a kernel memory corruption\n and possibly crash or lock up a system. Due to the\n nature of the flaw, a privilege escalation cannot be\n fully ruled out, although we believe it is unlikely.\n (CVE-2017-0861)\n\n - A race condition issue was found in the way the raw\n packet socket implementation in the Linux kernel\n networking subsystem handled synchronization. A local\n user able to open a raw packet socket (requires the\n CAP_NET_RAW capability) could use this to waste\n resources in the kernel's ring buffer or possibly cause\n an out-of-bounds read on the heap leading to a system\n crash. (CVE-2017-1000111)\n\n - A use-after-free flaw was found in the Netlink\n functionality of the Linux kernel networking subsystem.\n Due to the insufficient cleanup in the mq_notify\n function, a local attacker could potentially use this\n flaw to escalate their privileges on the system.\n (CVE-2017-11176)\n\n - It was found that in the Linux kernel through v4.14-rc5,\n bio_map_user_iov() and bio_unmap_user() in 'block/bio.c'\n do unbalanced pages refcounting if IO vector has small\n consecutive buffers belonging to the same page.\n bio_add_pc_page() merges them into one, but the page\n reference is never dropped, causing a memory leak and\n possible system lockup due to out-of-memory condition.\n (CVE-2017-12190)\n\n - A divide-by-zero vulnerability was found in the\n __tcp_select_window function in the Linux kernel. This\n can result in a kernel panic causing a local denial of\n service. (CVE-2017-14106)\n\n - A non-privileged user is able to mount a fuse filesystem\n on RHEL 6 or 7 and crash a system if an application\n punches a hole in a file that does not end aligned to a\n page boundary. (CVE-2017-15121)\n\n - A use-after-free vulnerability was found when issuing an\n ioctl to a sound device. This could allow a user to\n exploit a race condition and create memory corruption or\n possibly privilege escalation. (CVE-2017-15265)\n\n - The Linux kernel, before version 4.14.3, is vulnerable\n to a denial of service in\n drivers/md/dm.c:dm_get_from_kobject() which can be\n caused by local users leveraging a race condition with\n __dm_destroy() during creation and removal of DM\n devices. Only privileged local users (with CAP_SYS_ADMIN\n capability) can directly perform the ioctl operations\n for dm device creation and removal and this would\n typically be outside the direct control of the\n unprivileged attacker. (CVE-2017-18203)\n\n - A race condition leading to a NULL pointer dereference\n was found in the Linux kernel's Link Layer Control\n implementation. A local attacker with access to ping\n sockets could use this flaw to crash the system.\n (CVE-2017-2671)\n\n - It was found that the original fix for CVE-2016-6786 was\n incomplete. There exist a race between two concurrent\n sys_perf_event_open() calls when both try and move the\n same pre-existing software group into a hardware\n context. (CVE-2017-6001)\n\n - A flaw was found in the Linux kernel's handling of\n packets with the URG flag. Applications using the\n splice() and tcp_splice_read() functionality could allow\n a remote attacker to force the kernel to enter a\n condition in which it could loop indefinitely.\n (CVE-2017-6214)\n\n - Kernel memory corruption due to a buffer overflow was\n found in brcmf_cfg80211_mgmt_tx() function in Linux\n kernels from v3.9-rc1 to v4.13-rc1. The vulnerability\n can be triggered by sending a crafted NL80211_CMD_FRAME\n packet via netlink. This flaw is unlikely to be\n triggered remotely as certain userspace code is needed\n for this. An unprivileged local user could use this flaw\n to induce kernel memory corruption on the system,\n leading to a crash. Due to the nature of the flaw,\n privilege escalation cannot be fully ruled out, although\n it is unlikely. (CVE-2017-7541)\n\n - An integer overflow vulnerability in\n ip6_find_1stfragopt() function was found. A local\n attacker that has privileges (of CAP_NET_RAW) to open\n raw socket can cause an infinite loop inside the\n ip6_find_1stfragopt() function. (CVE-2017-7542)\n\n - Incorrect error handling in the set_mempolicy() and\n mbind() compat syscalls in 'mm/mempolicy.c' in the Linux\n kernel allows local users to obtain sensitive\n information from uninitialized stack data by triggering\n failure of a certain bitmap operation. (CVE-2017-7616)\n\n - The mm subsystem in the Linux kernel through 4.10.10\n does not properly enforce the CONFIG_STRICT_DEVMEM\n protection mechanism, which allows local users to read\n or write to kernel memory locations in the first\n megabyte (and bypass slab-allocation access\n restrictions) via an application that opens the /dev/mem\n file, related to arch/x86/mm/init.c and\n drivers/char/mem.c. (CVE-2017-7889)\n\n - The IPv6 fragmentation implementation in the Linux\n kernel does not consider that the nexthdr field may be\n associated with an invalid option, which allows local\n users to cause a denial of service (out-of-bounds read\n and BUG) or possibly have unspecified other impact via\n crafted socket and send system calls. Due to the nature\n of the flaw, privilege escalation cannot be fully ruled\n out, although we believe it is unlikely. (CVE-2017-9074)\n\n - In the Linux kernel versions 4.12, 3.10, 2.6, and\n possibly earlier, a race condition vulnerability exists\n in the sound system allowing for a potential deadlock\n and memory corruption due to use-after-free condition\n and thus denial of service. Due to the nature of the\n flaw, privilege escalation cannot be fully ruled out,\n although we believe it is unlikely. (CVE-2018-1000004)\n\n - A null pointer dereference in dccp_write_xmit() function\n in net/dccp/output.c in the Linux kernel allows a local\n user to cause a denial of service by a number of certain\n crafted system calls. (CVE-2018-1130)\n\n - Modern Intel microprocessors implement hardware-level\n micro-optimizations to improve the performance of\n writing data back to CPU caches. The write operation is\n split into STA (STore Address) and STD (STore Data) sub-\n operations. These sub-operations allow the processor to\n hand-off address generation logic into these sub-\n operations for optimized writes. Both of these sub-\n operations write to a shared distributed processor\n structure called the 'processor store buffer'. As a\n result, an unprivileged attacker could use this flaw to\n read private data resident within the CPU's processor\n store buffer. (CVE-2018-12126)\n\n - Microprocessors use a load port subcomponent to\n perform load operations from memory or IO. During a load\n operation, the load port receives data from the memory\n or IO subsystem and then provides the data to the CPU\n registers and operations in the CPUs pipelines. Stale\n load operations results are stored in the 'load port'\n table until overwritten by newer operations. Certain\n load-port operations triggered by an attacker can be\n used to reveal data about previous stale requests\n leaking data back to the attacker via a timing side-\n channel. (CVE-2018-12127)\n\n - A flaw was found in the implementation of the fill\n buffer, a mechanism used by modern CPUs when a cache-\n miss is made on L1 CPU cache. If an attacker can\n generate a load operation that would create a page\n fault, the execution will continue speculatively with\n incorrect data from the fill buffer while the data is\n fetched from higher level caches. This response time can\n be measured to infer data in the fill buffer.\n (CVE-2018-12130)\n\n - A vulnerability was found in the\n fs/inode.c:inode_init_owner() function logic of the\n LInux kernel that allows local users to create files\n with an unintended group ownership and with group\n execution and SGID permission bits set, in a scenario\n where a directory is SGID and belongs to a certain group\n and is writable by a user who is not a member of this\n group. This can lead to excessive permissions granted in\n case when they should not. (CVE-2018-13405)\n\n - A Floating Point Unit (FPU) state information leakage\n flaw was found in the way the Linux kernel saved and\n restored the FPU state during task switch. Linux kernels\n that follow the Lazy FPU Restore scheme are vulnerable\n to the FPU state information leakage issue. An\n unprivileged local attacker could use this flaw to read\n FPU state bits by conducting targeted cache side-channel\n attacks, similar to the Meltdown vulnerability disclosed\n earlier this year. (CVE-2018-3665)\n\n - An error in the _sctp_make_chunk() function\n (net/sctp/sm_make_chunk.c) when handling SCTP, packet\n length can be exploited by a malicious local user to\n cause a kernel crash and a DoS. (CVE-2018-5803)\n\n - ALSA sequencer core initializes the event pool on demand\n by invoking snd_seq_pool_init() when the first write\n happens and the pool is empty. A user can reset the pool\n size manually via ioctl concurrently, and this may lead\n to UAF or out-of-bound access. (CVE-2018-7566)\n\n - Uncacheable memory on some microprocessors utilizing\n speculative execution may allow an authenticated user to\n potentially enable information disclosure via a side\n channel with local access.

CVE-2016-4470: The key_reject_and_link function in\n security/keys/key.c in the Linux kernel did not ensure\n that a certain data structure is initialized, which\n allowed local users to cause a denial of service (system\n crash) via vectors involving a crafted keyctl request2\n command (bnc#984755).\n\nThe update package also includes non-security fixes. See advisory for\ndetails.\n\nNote that Tenable Network Security has extracted the preceding\ndescription block directly from the SUSE security advisory. Tenable\nhas attempted to automatically clean and format it as much as possible\nwithout introducing additional issues.\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n
