The vulnerability is present only if the usb-midi module is enabled, but as far as I can see many modern distributions do this. The bug has been fixed upstream (https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=07d86ca93db7e5cdf4743564d98292042ec21af7).\n\nThe vulnerability can be exploited in two ways:\n\n- Denial of service. Requires physical access (ability to plug in a malicious USB device). All the kernel versions seem to be vulnerable to this attack. I managed to cause a kernel panic on real machines with the following kernels: Ubuntu 14.04 (3.19.0-49-generic), Linux Mint 17.3 (3.19.0-32-generic), Fedora 22 (4.1.5-200.fe22.x86_64) and CentOS 6 (2.6.32-584.12.2.e16.x86_64).\n\n- Arbitrary code execution with ring 0 privileges (and therefore a privilege escalation). Requires both physical and local access (ability to plug in a malicious USB device and to execute a malicious binary as a non-privileged user). All the kernel versions starting from v3.0 seem to be vulnerable to this attack. I managed to gain root privileges on real machines with the following kernels: Ubuntu 14.04 (3.19.0-49-generic), Linux Mint 17.3 (3.19.0-32-generic) and Fedora 22 (4.1.5-200.fe22.x86_64). All machines had SMEP turned on, but didn't have SMAP.\n\nA proof-of-concept exploit (poc.c - https://github.com/xairy/kernel-exploits/blob/master/CVE-2016-2384/poc.c, poc.py - https://github.com/xairy/kernel-exploits/blob/master/CVE-2016-2384/poc.py) is provided for both types of attacks. The provided exploit uses a Facedancer21 (http://goodfet.sourceforge.net/hardware/facedancer21/) board to physically emulate the malicious USB device.

The vulnerability is present only if the usb-midi module is enabled, but as far as I can see many modern distributions do this. The bug has been fixed upstream (https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=07d86ca93db7e5cdf4743564d98292042ec21af7).\r\n \r\nThe vulnerability can be exploited in two ways:\r\n \r\n- Denial of service. Requires physical access (ability to plug in a malicious USB device). All the kernel versions seem to be vulnerable to this attack. I managed to cause a kernel panic on real machines with the following kernels: Ubuntu 14.04 (3.19.0-49-generic), Linux Mint 17.3 (3.19.0-32-generic), Fedora 22 (4.1.5-200.fe22.x86_64) and CentOS 6 (2.6.32-584.12.2.e16.x86_64).\r\n \r\n- Arbitrary code execution with ring 0 privileges (and therefore a privilege escalation). Requires both physical and local access (ability to plug in a malicious USB device and to execute a malicious binary as a non-privileged user). All the kernel versions starting from v3.0 seem to be vulnerable to this attack. I managed to gain root privileges on real machines with the following kernels: Ubuntu 14.04 (3.19.0-49-generic), Linux Mint 17.3 (3.19.0-32-generic) and Fedora 22 (4.1.5-200.fe22.x86_64). All machines had SMEP turned on, but didn't have SMAP.\r\n \r\nA proof-of-concept exploit (poc.c - https://github.com/xairy/kernel-exploits/blob/master/CVE-2016-2384/poc.c, poc.py - https://github.com/xairy/kernel-exploits/blob/master/CVE-2016-2384/poc.py) is provided for both types of attacks. The provided exploit uses a Facedancer21 (http://goodfet.sourceforge.net/hardware/facedancer21/) board to physically emulate the malicious USB device. The provided exploit bypasses SMEP, but doesn't bypass SMAP (though it might be possible to do). It has about 50% success rate (the kernel crashes on failure), but this can probably be improved. Check out the demo video (https://www.youtube.com/watch?v=lfl1NJn1nvo).\r\n \r\nIt should actually be possible to make the entire exploit for the arbitrary code execution hardware only and therefore eliminate the local access requirement, but this approach wasn't thoroughly investigated.\r\n \r\nThe vulnerability was found with KASAN (https://github.com/google/kasan) (KernelAddressSanitizer, a kernel memory error detector) and vUSBf (https://github.com/schumilo/vUSBf) (a virtual usb fuzzer).\r\n \r\n \r\n--- poc.c ---\r\n// A part of the proof-of-concept exploit for the vulnerability in the usb-midi\r\n// driver.

The vulnerability is present only if the usb-midi module is enabled, but as far as I can see many modern distributions do this. The bug has been fixed upstream (https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=07d86ca93db7e5cdf4743564d98292042ec21af7). \n \nThe vulnerability can be exploited in two ways: \n \n- Denial of service. Requires physical access (ability to plug in a malicious USB device). All the kernel versions seem to be vulnerable to this attack. I managed to cause a kernel panic on real machines with the following kernels: Ubuntu 14.04 (3.19.0-49-generic), Linux Mint 17.3 (3.19.0-32-generic), Fedora 22 (4.1.5-200.fe22.x86_64) and CentOS 6 (2.6.32-584.12.2.e16.x86_64). \n \n- Arbitrary code execution with ring 0 privileges (and therefore a privilege escalation). Requires both physical and local access (ability to plug in a malicious USB device and to execute a malicious binary as a non-privileged user). All the kernel versions starting from v3.0 seem to be vulnerable to this attack. I managed to gain root privileges on real machines with the following kernels: Ubuntu 14.04 (3.19.0-49-generic), Linux Mint 17.3 (3.19.0-32-generic) and Fedora 22 (4.1.5-200.fe22.x86_64). All machines had SMEP turned on, but didn't have SMAP. \n \nA proof-of-concept exploit (poc.c - https://github.com/xairy/kernel-exploits/blob/master/CVE-2016-2384/poc.c, poc.py - https://github.com/xairy/kernel-exploits/blob/master/CVE-2016-2384/poc.py) is provided for both types of attacks. The provided exploit uses a Facedancer21 (http://goodfet.sourceforge.net/hardware/facedancer21/) board to physically emulate the malicious USB device. The provided exploit bypasses SMEP, but doesn't bypass SMAP (though it might be possible to do). It has about 50% success rate (the kernel crashes on failure), but this can probably be improved. Check out the demo video (https://www.youtube.com/watch?v=lfl1NJn1nvo). \n \nIt should actually be possible to make the entire exploit for the arbitrary code execution hardware only and therefore eliminate the local access requirement, but this approach wasn't thoroughly investigated. \n \nThe vulnerability was found with KASAN (https://github.com/google/kasan) (KernelAddressSanitizer, a kernel memory error detector) and vUSBf (https://github.com/schumilo/vUSBf) (a virtual usb fuzzer). \n \n \n--- poc.c --- \n// A part of the proof-of-concept exploit for the vulnerability in the usb-midi \n// driver.

Whenever it could not send a packet because the network was congested, it would free the packet buffer but later attempt to send the packet again. This use-after-free could result in a denial of service (crash or hang), data loss or privilege escalation.\n\nCVE-2016-0774\n\nIt was found that the fix for CVE-2015-1805 in kernel versions older than Linux 3.16 did not correctly handle the case of a partially failed atomic read. A local, unprivileged user could use this flaw to crash the system or leak kernel memory to user space.\n\nCVE-2016-2384\n\nAndrey Konovalov found that a USB MIDI device with an invalid USB descriptor could trigger a double-free. This may be used by a physically present user for privilege escalation.\n\nAdditionally, it fixes some old security issues with no CVE ID :\n\nSeveral kernel APIs permitted reading or writing 2 GiB of data or more in a single chunk, which could lead to an integer overflow when applied to certain filesystems, socket or device types. The full security impact has not been evaluated.\n\nFinally, it fixes a regression in 2.6.32-48squeeze17 that would cause Samba to hang in some situations.\n\nFor the oldoldstable distribution (squeeze), these problems have been fixed in version 2.6.32-48squeeze20.

Whenever it could\nnot send a packet because the network was congested, it would free the\npacket buffer but later attempt to send the packet again. This\nuse-after-free could result in a denial of service (crash or hang),\ndata loss or privilege escalation.\n\nCVE-2016-0774\n\nIt was found that the fix for CVE-2015-1805 in kernel versions older\nthan Linux 3.16 did not correctly handle the case of a partially\nfailed atomic read. A local, unprivileged user could use this flaw to\ncrash the system or leak kernel memory to user space.\n\nCVE-2016-2384\n\nAndrey Konovalov found that a USB MIDI device with an invalid USB\ndescriptor could trigger a double-free. This may be used by a\nphysically present user for privilege escalation.\n\nAdditionally, it fixes some old security issues with no CVE ID :\n\nSeveral kernel APIs permitted reading or writing 2 GiB of data or more\nin a single chunk, which could lead to an integer overflow when\napplied to certain filesystems, socket or device types. The full\nsecurity impact has not been evaluated.\n\nFinally, it fixes a regression in 2.6.32-48squeeze17 that would cause\nSamba to hang in some situations.\n\nFor the oldoldstable distribution (squeeze), these problems have been\nfixed in version 2.6.32-48squeeze20. This is *really* the final update\nto the linux-2.6 package for squeeze.\n\nFor the oldstable distribution (wheezy), the kernel was not affected\nby the integer overflow issues and the remaining problems will be\nfixed in version 3.2.73-2+deb7u3.\n\nFor the stable distribution (jessie), the kernel was not affected by\nthe integer overflow issues or CVE-2016-0774, and the remaining\nproblems will be fixed in version 3.16.7-ckt20-1+deb8u4.\n\nNOTE: Tenable Network Security has extracted the preceding description\nblock directly from the DLA security advisory.

"An update for kernel is now available for Red Hat Enterprise Linux 6.\n\nRed Hat Product Security has rated this update as having a security impact of Moderate. 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().

A Common Vulnerability Scoring System (CVSS) base\nscore, which gives a detailed severity rating, is available for each\nvulnerability from the CVE link(s) in the References section.\n\nThe kernel packages contain the Linux kernel, the core of any Linux\noperating system.\n\nSecurity Fix(es) :\n\n* It was discovered that a remote attacker could leverage the\ngeneration of IPv6 atomic fragments to trigger the use of\nfragmentation in an arbitrary IPv6 flow (in scenarios in which actual\nfragmentation of packets is not needed) and could subsequently perform\nany type of a fragmentation-based attack against legacy IPv6 nodes\nthat do not implement RFC6946. (CVE-2016-10142, Moderate)\n\n* A flaw was discovered in the way the Linux kernel dealt with paging\nstructures. When the kernel invalidated a paging structure that was\nnot in use locally, it could, in principle, race against another CPU\nthat is switching to a process that uses the paging structure in\nquestion. A local user could use a thread running with a stale cached\nvirtual->physical translation to potentially escalate their privileges\nif the translation in question were writable and the physical page got\nreused 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\nthe Linux kernel's aacraid implementation. A local attacker could use\nthis flaw to cause a denial of service (out-of-bounds access or system\ncrash) by changing a certain size value. (CVE-2016-6480, Moderate)\n\n* It was found that when the gcc stack protector was enabled, reading\nthe /proc/keys file could cause a panic in the Linux kernel due to\nstack corruption. This happened because an incorrect buffer size was\nused to hold a 64-bit timeout value rendered as weeks. (CVE-2016-7042,\nModerate)\n\n* It was found that when file permissions were modified via chmod and\nthe user modifying them was not in the owning group or capable of\nCAP_FSETID, the setgid bit would be cleared. Setting a POSIX ACL via\nsetxattr sets the file permissions as well as the new ACL, but doesn't\nclear the setgid bit in a similar way. This could allow a local user\nto 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\nattacker with CAP_NET_ADMIN capabilities could cause an out-of-bounds\nmemory access by creating a smaller-than-expected ICMP header and\nsending 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\nkernel's block device implementation did not properly restrict the\ntype of iterator, which could allow a local attacker to read or write\nto arbitrary kernel memory locations or cause a denial of service\n(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\nerror could be triggered for the 'umidi' object.

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.\n 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.\n (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. (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. (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.

(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.

Enterprise Linux 6.\n\nRed Hat Product Security has rated this update as having a security impact of Moderate. 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. An attacker with physical access to the system could use this flaw to escalate their privileges.

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 (!

(CVE-2016-2384)\n\n - The Linux kernel version 3.3-rc1 and later is affected by a vulnerability lies in the processing of incoming L2CAP commands - ConfigRequest, and ConfigResponse messages. This info leak is a result of uninitialized stack variables that may be returned to an attacker in their uninitialized state. By manipulating the code flows that precede the handling of these configuration messages, an attacker can also gain some control over which data will be held in the uninitialized stack variables. This can allow him to bypass KASLR, and stack canaries protection - as both pointers and stack canaries may be leaked in this manner. Combining this vulnerability (for example) with the previously disclosed RCE vulnerability in L2CAP configuration parsing (CVE-2017-1000251) may allow an attacker to exploit the RCE against kernels which were built with the above mitigations. These are the specifics of this vulnerability: In the function l2cap_parse_conf_rsp and in the function l2cap_parse_conf_req the following variable is declared without initialization: struct l2cap_conf_efs efs; In addition, when parsing input configuration parameters in both of these functions, the switch case for handling EFS elements may skip the memcpy call that will write to the efs variable: ... case L2CAP_CONF_EFS: if (olen == sizeof(efs)) memcpy(&efs;, (void\n *)val, olen); ... The olen in the above if is attacker controlled, and regardless of that if, in both of these functions the efs variable would eventually be added to the outgoing configuration request that is being built: l2cap_add_conf_opt(&ptr;, L2CAP_CONF_EFS, sizeof(efs), (unsigned long) &efs;); So by sending a configuration request, or response, that contains an L2CAP_CONF_EFS element, but with an element length that is not sizeof(efs) - the memcpy to the uninitialized efs variable can be avoided, and the uninitialized variable would be returned to the attacker (16 bytes). (CVE-2017-1000410)\n\n - The Linux Kernel version 3.18 contains a dangerous feature vulnerability in modify_user_hw_breakpoint() that can result in crash and possibly memory corruption. This attack appear to be exploitable via local code execution and the ability to use ptrace. This vulnerability appears to have been fixed in git commit f67b15037a7a50c57f72e69a6d59941ad90a0f0f. (CVE-2018-1000199)\n\n - The KVM implementation in the Linux kernel through 4.14.7 allows attackers to obtain potentially sensitive information from kernel memory, aka a write_mmio stack-based out-of-bounds read, related to arch/x86/kvm/x86.c and include/trace/events/kvm.h. (CVE-2017-17741)\n\n - The xfs_bmap_extents_to_btree function in fs/xfs/libxfs/xfs_bmap.c in the Linux kernel through 4.16.3 allows local users to cause a denial of service (xfs_bmapi_write NULL pointer dereference) via a crafted xfs image. (CVE-2018-10323)\n\n - System software utilizing Lazy FP state restore technique on systems using Intel Core-based microprocessors may potentially allow a local process to infer data from another process through a speculative execution side channel. (CVE-2018-3665)\n\n - The snd_seq_ioctl_remove_events function in sound/core/seq/seq_clientmgr.c in the Linux kernel before 4.4.1 does not verify FIFO assignment before proceeding with FIFO clearing, which allows local users to cause a denial of service (NULL pointer dereference and OOPS) via a crafted ioctl call. (CVE-2016-2543)\n\n - sound/core/hrtimer.c in the Linux kernel before 4.4.1 does not prevent recursive callback access, which allows local users to cause a denial of service (deadlock) via a crafted ioctl call. (CVE-2016-2549)\n\n - Race condition in the queue_delete function in sound/core/seq/seq_queue.c in the Linux kernel before 4.4.1 allows local users to cause a denial of service (use-after-free and system crash) by making an ioctl call at a certain time. (CVE-2016-2544)\n\n - The snd_timer_interrupt function in sound/core/timer.c in the Linux kernel before 4.4.1 does not properly maintain a certain linked list, which allows local users to cause a denial of service (race condition and system crash) via a crafted ioctl call. (CVE-2016-2545)\n\n - sound/core/timer.c in the Linux kernel before 4.4.1 employs a locking approach that does not consider slave timer instances, which allows local users to cause a denial of service (race condition, use-after- free, and system crash) via a crafted ioctl call.

"description": "The openSUSE 13.1 kernel was updated to 3.12.57 to receive various security and bugfixes.\n\nThe following security bugs were fixed :\n\n - CVE-2015-8785: The fuse_fill_write_pages function in fs/fuse/file.c in the Linux kernel allowed local users to cause a denial of service (infinite loop) via a writev system call that triggers a zero length for the first segment of an iov. (bsc#963765)\n\n - CVE-2015-8551: The PCI backend driver in Xen, when running on an x86 system and using Linux as the driver domain, allowed local guest administrators to hit BUG conditions and cause a denial of service (NULL pointer dereference and host OS crash) by leveraging a system with access to a passed-through MSI or MSI-X capable physical PCI device and a crafted sequence of XEN_PCI_OP_* operations, aka 'Linux pciback missing sanity checks (bnc#957990).\n\n - CVE-2015-8552: The PCI backend driver in Xen, when running on an x86 system and using Linux as the driver domain, allowed local guest administrators to generate a continuous stream of WARN messages and cause a denial of service (disk consumption) by leveraging a system with access to a passed-through MSI or MSI-X capable physical PCI device and XEN_PCI_OP_enable_msi operations, aka 'Linux pciback missing sanity checks (bnc#957990).\n\n - CVE-2015-8812: A flaw was found in the CXGB3 kernel driver when the network was considered congested. The kernel would incorrectly misinterpret the congestion as an error condition and incorrectly free/clean up the skb. When the device would then send the skb's queued, these structures would be referenced and may panic the system or allow an attacker to escalate privileges in a use-after-free scenario.(bsc#966437).\n\n - CVE-2015-8816: A malicious USB device could cause kernel crashes in the in hub_activate() function (bnc#968010).\n\n - CVE-2016-0723: Race condition in the tty_ioctl function in drivers/tty/tty_io.c in the Linux kernel allowed local users to obtain sensitive information from kernel memory or cause a denial of service (use-after-free and system crash) by making a TIOCGETD ioctl call during processing of a TIOCSETD ioctl call. (bsc#961500)\n\n - CVE-2016-2184: A malicious USB device could cause kernel crashes in the alsa usb-audio device driver (bsc#971125).\n\n - CVE-2016-2384: A double free on the ALSA umidi object was fixed. (bsc#966693).\n\n - CVE-2016-2782: A malicious USB device could cause kernel crashes in the visor device driver (bnc#968670).\n\n - CVE-2016-3139: A malicious USB device could cause kernel crashes in the wacom device driver (bnc#970909).\n\n - CVE-2016-3156: A quadratic algorithm could lead to long kernel ipv4 hangs when removing a device with a large number of addresses.

bugfixes.\n\nThe following security bugs were fixed :\n\n - CVE-2015-8785: The fuse_fill_write_pages function in\n fs/fuse/file.c in the Linux kernel allowed local users\n to cause a denial of service (infinite loop) via a\n writev system call that triggers a zero length for the\n first segment of an iov. (bsc#963765)\n\n - CVE-2015-8551: The PCI backend driver in Xen, when\n running on an x86 system and using Linux as the driver\n domain, allowed local guest administrators to hit BUG\n conditions and cause a denial of service (NULL pointer\n dereference and host OS crash) by leveraging a system\n with access to a passed-through MSI or MSI-X capable\n physical PCI device and a crafted sequence of\n XEN_PCI_OP_* operations, aka 'Linux pciback missing\n sanity checks (bnc#957990).\n\n - CVE-2015-8552: The PCI backend driver in Xen, when\n running on an x86 system and using Linux as the driver\n domain, allowed local guest administrators to generate a\n continuous stream of WARN messages and cause a denial of\n service (disk consumption) by leveraging a system with\n access to a passed-through MSI or MSI-X capable physical\n PCI device and XEN_PCI_OP_enable_msi operations, aka\n 'Linux pciback missing sanity checks (bnc#957990).\n\n - CVE-2015-8812: A flaw was found in the CXGB3 kernel\n driver when the network was considered congested. The\n kernel would incorrectly misinterpret the congestion as\n an error condition and incorrectly free/clean up the\n skb. When the device would then send the skb's queued,\n these structures would be referenced and may panic the\n system or allow an attacker to escalate privileges in a\n use-after-free scenario.(bsc#966437).\n\n - CVE-2015-8816: A malicious USB device could cause kernel\n crashes in the in hub_activate() function (bnc#968010).\n\n - CVE-2016-0723: Race condition in the tty_ioctl function\n in drivers/tty/tty_io.c in the Linux kernel allowed\n local users to obtain sensitive information from kernel\n memory or cause a denial of service (use-after-free and\n system crash) by making a TIOCGETD ioctl call during\n processing of a TIOCSETD ioctl call. (bsc#961500)\n\n - CVE-2016-2184: A malicious USB device could cause kernel\n crashes in the alsa usb-audio device driver\n (bsc#971125).\n\n - CVE-2016-2384: A double free on the ALSA umidi object\n was fixed. (bsc#966693).\n\n - CVE-2016-2782: A malicious USB device could cause kernel\n crashes in the visor device driver (bnc#968670).\n\n - CVE-2016-3139: A malicious USB device could cause kernel\n crashes in the wacom device driver (bnc#970909).\n\n - CVE-2016-3156: A quadratic algorithm could lead to long\n kernel ipv4 hangs when removing a device with a large\n number of addresses.

The new kernel version in both suites includes that mitigation plus limits on the total size of pipe buffers allocated for each user.\n\n - CVE-2015-7566 Ralf Spenneberg of OpenSource Security reported that the visor driver crashes when a specially crafted USB device without bulk-out endpoint is detected.\n\n - CVE-2015-8767 An SCTP denial-of-service was discovered which can be triggered by a local attacker during a heartbeat timeout event after the 4-way handshake.\n\n - CVE-2015-8785 It was discovered that local users permitted to write to a file on a FUSE filesystem could cause a denial of service (unkillable loop in the kernel).\n\n - CVE-2015-8812 A flaw was found in the iw_cxgb3 Infiniband driver.\n Whenever it could not send a packet because the network was congested, it would free the packet buffer but later attempt to send the packet again. This use-after-free could result in a denial of service (crash or hang), data loss or privilege escalation.\n\n - CVE-2015-8816 A use-after-free vulnerability was discovered in the USB hub driver. This may be used by a physically present user for privilege escalation.\n\n - CVE-2015-8830 Ben Hawkes of Google Project Zero reported that the AIO interface permitted reading or writing 2 GiB of data or more in a single chunk, which could lead to an integer overflow when applied to certain filesystems, socket or device types. The full security impact has not been evaluated.\n\n - CVE-2016-0723 A use-after-free vulnerability was discovered in the TIOCGETD ioctl. A local attacker could use this flaw for denial-of-service.\n\n - CVE-2016-0774 It was found that the fix for CVE-2015-1805 in kernel versions older than Linux 3.16 did not correctly handle the case of a partially failed atomic read. A local, unprivileged user could use this flaw to crash the system or leak kernel memory to user space.\n\n - CVE-2016-2069 Andy Lutomirski discovered a race condition in flushing of the TLB when switching tasks on an x86 system. On an SMP system this could possibly lead to a crash, information leak or privilege escalation.\n\n - CVE-2016-2384 Andrey Konovalov found that a crafted USB MIDI device with an invalid USB descriptor could trigger a double-free. This may be used by a physically present user for privilege escalation.\n\n - CVE-2016-2543 Dmitry Vyukov found that the core sound sequencer driver (snd-seq) lacked a necessary check for a NULL pointer, allowing a user with access to a sound sequencer device to cause a denial-of service (crash).\n\n - CVE-2016-2544, CVE-2016-2546, CVE-2016-2547, CVE-2016-2548\n\n Dmitry Vyukov found various race conditions in the sound subsystem (ALSA)'s management of timers. A user with access to sound devices could use these to cause a denial-of-service (crash or hang) or possibly for privilege escalation.\n\n - CVE-2016-2545 Dmitry Vyukov found a flaw in list manipulation in the sound subsystem (ALSA)'s management of timers. A user with access to sound devices could use this to cause a denial-of-service (crash or hang) or possibly for privilege escalation.\n\n - CVE-2016-2549 Dmitry Vyukov found a potential deadlock in the sound subsystem (ALSA)'s use of high resolution timers.

The\n new kernel version in both suites includes that mitigation plus\n limits on the total size of pipe buffers allocated for each user.\n\n - CVE-2015-7566\n Ralf Spenneberg of OpenSource Security reported that the\n visor driver crashes when a specially crafted USB device\n without bulk-out endpoint is detected.\n\n - CVE-2015-8767\n An SCTP denial-of-service was discovered which can be\n triggered by a local attacker during a heartbeat timeout\n event after the 4-way handshake.\n\n - CVE-2015-8785\n It was discovered that local users permitted to write to\n a file on a FUSE filesystem could cause a denial of\n service (unkillable loop in the kernel).\n\n - CVE-2015-8812\n A flaw was found in the iw_cxgb3 Infiniband driver.\n Whenever it could not send a packet because the network\n was congested, it would free the packet buffer but later\n attempt to send the packet again. This use-after-free\n could result in a denial of service (crash or hang),\n data loss or privilege escalation.\n\n - CVE-2015-8816\n A use-after-free vulnerability was discovered in the USB\n hub driver. This may be used by a physically present\n user for privilege escalation.\n\n - CVE-2015-8830\n Ben Hawkes of Google Project Zero reported that the AIO\n interface permitted reading or writing 2 GiB of data or\n more in a single chunk, which could lead to an integer\n overflow when applied to certain filesystems, socket or\n device types. The full security impact has not been\n evaluated.\n\n - CVE-2016-0723\n A use-after-free vulnerability was discovered in the\n TIOCGETD ioctl. A local attacker could use this flaw for\n denial-of-service.\n\n - CVE-2016-0774\n It was found that the fix for CVE-2015-1805 in kernel\n versions older than Linux 3.16 did not correctly handle\n the case of a partially failed atomic read. A local,\n unprivileged user could use this flaw to crash the\n system or leak kernel memory to user space.\n\n - CVE-2016-2069\n Andy Lutomirski discovered a race condition in flushing\n of the TLB when switching tasks on an x86 system. On an\n SMP system this could possibly lead to a crash,\n information leak or privilege escalation.\n\n - CVE-2016-2384\n Andrey Konovalov found that a crafted USB MIDI device\n with an invalid USB descriptor could trigger a\n double-free. This may be used by a physically present\n user for privilege escalation.\n\n - CVE-2016-2543\n Dmitry Vyukov found that the core sound sequencer driver\n (snd-seq) lacked a necessary check for a NULL pointer,\n allowing a user with access to a sound sequencer device\n to cause a denial-of service (crash).\n\n - CVE-2016-2544, CVE-2016-2546, CVE-2016-2547,\n CVE-2016-2548\n\n Dmitry Vyukov found various race conditions in the sound\n subsystem (ALSA)'s management of timers. A user with\n access to sound devices could use these to cause a\n denial-of-service (crash or hang) or possibly for\n privilege escalation.\n\n - CVE-2016-2545\n Dmitry Vyukov found a flaw in list manipulation in the\n sound subsystem (ALSA)'s management of timers. A user\n with access to sound devices could use this to cause a\n denial-of-service (crash or hang) or possibly for\n privilege escalation.\n\n - CVE-2016-2549\n Dmitry Vyukov found a potential deadlock in the sound\n subsystem (ALSA)'s use of high resolution timers. A user\n with access to sound devices could use this to cause a\n denial-of-service (hang).\n\n - CVE-2016-2550\n The original mitigation of CVE-2013-4312, limiting the\n total number of files a user could queue on local\n sockets, was flawed. A user given a local socket opened\n by another user, for example through the systemd socket\n activation mechanism, could make use of the other user's\n quota, again leading to a denial-of-service (resource\n exhaustion).

use-after-free flaw was found in the way the Linux kernel's key management subsystem handled keyring object reference counting in certain error path of the join_session_keyring() function. A local, unprivileged user could use this flaw to escalate their privileges on the system.(CVE-2016-0728)\n\n - A flaw was found in the way the Linux kernel's ASN.1 DER decoder processed certain certificate files with tags of indefinite length. A local, unprivileged user could use a specially crafted X.509 certificate DER file to crash the system or, potentially, escalate their privileges on the system.(CVE-2016-0758)\n\n - The LIST_POISON feature in include/linux/poison.h in the Linux kernel before 4.3, as used in Android 6.0.1 before 2016-03-01, does not properly consider the relationship to the mmap_min_addr value, which makes it easier for attackers to bypass a poison-pointer protection mechanism by triggering the use of an uninitialized list entry, aka Android internal bug 26186802, a different vulnerability than CVE-2015-3636.(CVE-2016-0821)\n\n - The pagemap_open function in fs/proc/task_mmu.c in the Linux kernel before 3.19.3, as used in Android 6.0.1 before 2016-03-01, allows local users to obtain sensitive physical-address information by reading a pagemap file, aka Android internal bug 25739721.(CVE-2016-0823)\n\n - The aio_mount function in fs/aio.c in the Linux kernel does not properly restrict execute access, which makes it easier for local users to bypass intended SELinux W^X policy restrictions.(CVE-2016-10044)\n\n - It was found that the fix for CVE-2016-9576 was incomplete: the Linux kernel's sg implementation did not properly restrict write operations in situations where the KERNEL_DS option is set. 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-2016-10088)\n\n - A use-after-free flaw was found in the Linux kernel which enables a race condition in the L2TPv3 IP Encapsulation feature. A local user could use this flaw to escalate their privileges or crash the system.(CVE-2016-10200)\n\n - Mounting a crafted EXT4 image read-only leads to an attacker controlled memory corruption and SLAB-Out-of-Bounds reads.(CVE-2016-10208)\n\n - The Linux kernel allows remote attackers to execute arbitrary code via UDP traffic that triggers an unsafe second checksum calculation during execution of a recv system call with the MSG_PEEK flag. This may create a kernel panic or memory corruption leading to privilege escalation.(CVE-2016-10229)\n\n - The overlayfs implementation in the Linux kernel through 4.5.2 does not properly maintain POSIX ACL xattr data, which allows local users to gain privileges by leveraging a group-writable setgid directory.(CVE-2016-1575)\n\n - The overlayfs implementation in the Linux kernel through 4.5.2 does not properly restrict the mount namespace, which allows local users to gain privileges by mounting an overlayfs filesystem on top of a FUSE filesystem, and then executing a crafted setuid program.(CVE-2016-1576)\n\n - A syntax vulnerability was discovered in the kernel's ASN1.1 DER decoder, which could lead to memory corruption or a complete local denial of service through x509 certificate DER files. A local system user could use a specially created key file to trigger BUG_ON() in the public_key_verify_signature() function (crypto/asymmetric_keys/public_key.c), to cause a kernel panic and crash the system.(CVE-2016-2053)\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-i1/4zphysical 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).(CVE-2016-2069)\n\n - A divide-by-zero vulnerability was found in a way the kernel processes TCP connections. The error can occur if a connection starts another cwnd reduction phase by setting tp-i1/4zprior_cwnd to the current cwnd (0) in tcp_init_cwnd_reduction(). A remote, unauthenticated attacker could use this flaw to crash the kernel (denial of service).(CVE-2016-2070)\n\n - It was discovered that the atl2_probe() function in the Atheros L2 Ethernet driver in the Linux kernel incorrectly enabled scatter/gather I/O. A remote attacker could use this flaw to obtain potentially sensitive information from the kernel memory.(CVE-2016-2117)\n\n - The create_fixed_stream_quirk function in sound/usb/quirks.c in the snd-usb-audio driver in the Linux kernel before 4.5.1 allows physically proximate attackers to cause a denial of service (NULL pointer dereference or double free, and system crash) via a crafted endpoints value in a USB device descriptor.(CVE-2016-2184)\n\n - The ati_remote2_probe function in drivers/input/misc/ati_remote2.c in the Linux kernel before 4.5.1 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted endpoints value in a USB device descriptor.(CVE-2016-2185)\n\n - The powermate_probe function in drivers/input/misc/powermate.c in the Linux kernel before 4.5.1 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted endpoints value in a USB device descriptor.(CVE-2016-2186)\n\n - The gtco_probe function in drivers/input/tablet/gtco.c in the Linux kernel through 4.5.2 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted endpoints value in a USB device descriptor.(CVE-2016-2187)\n\n - The iowarrior_probe function in drivers/usb/misc/iowarrior.c in the Linux kernel before 4.5.1 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted endpoints value in a USB device descriptor.(CVE-2016-2188)\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 could use this flaw to escalate their privileges.(CVE-2016-2384)\n\n - The snd_seq_ioctl_remove_events function in sound/core/seq/seq_clientmgr.c in the Linux kernel before 4.4.1 does not verify FIFO assignment before proceeding with FIFO clearing, which allows local users to cause a denial of service (NULL pointer dereference and OOPS) via a crafted ioctl call.(CVE-2016-2543)\n\n - Race condition in the queue_delete function in sound/core/seq/seq_queue.c in the Linux kernel before 4.4.1 allows local users to cause a denial of service (use-after-free and system crash) by making an ioctl call at a certain time.(CVE-2016-2544)\n\nNote that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory.

A local attacker could abuse concurrent access to the\nsocket options to escalate their privileges, or cause a denial of\nservice (use-after-free and system crash) via a crafted sendmsg system\ncall. (CVE-2016-3841, Important)\n\n* Several Moderate and Low impact security issues were found in the\nLinux kernel. Space precludes documenting each of these issues in this\nadvisory.

(CVE-2016-2847)\n\n - fs/btrfs/inode.c in the Linux kernel before 4.3.3 mishandles compressed inline extents, which allows local users to obtain sensitive pre-truncation information from a file via a clone action. (CVE-2015-8374)\n\n - Multiple heap-based buffer overflows in the hiddev_ioctl_usage function in drivers/hid/usbhid/hiddev.c in the Linux kernel through 4.6.3 allow local users to cause a denial of service or possibly have unspecified other impact via a crafted (1) HIDIOCGUSAGES or (2) HIDIOCSUSAGES ioctl call. (CVE-2016-5829)\n\n - The signal implementation in the Linux kernel before 4.3.5 on powerpc platforms does not check for an MSR with both the S and T bits set, which allows local users to cause a denial of service (TM Bad Thing exception and panic) via a crafted application. (CVE-2015-8844)\n\n - The tm_reclaim_thread function in arch/powerpc/kernel/process.c in the Linux kernel before 4.4.1 on powerpc platforms does not ensure that TM suspend mode exists before proceeding with a tm_reclaim call, which allows local users to cause a denial of service (TM Bad Thing exception and panic) via a crafted application. (CVE-2015-8845)\n\n - The rfcomm_sock_bind function in net/bluetooth/rfcomm/sock.c in the Linux kernel before 4.2 allows local users to obtain sensitive information or cause a denial of service (NULL pointer dereference) via vectors involving a bind system call on a Bluetooth RFCOMM socket. (CVE-2015-8956)\n\n - The asn1_ber_decoder function in lib/asn1_decoder.c in the Linux kernel before 4.3 allows attackers to cause a denial of service (panic) via an ASN.1 BER file that lacks a public key, leading to mishandling by the public_key_verify_signature function in crypto/asymmetric_keys/public_key.c. (CVE-2016-2053)\n\n - Double free vulnerability in the snd_usbmidi_create function in sound/usb/midi.c in the Linux kernel before 4.5 allows physically proximate attackers to cause a denial of service (panic) or possibly have unspecified other impact via vectors involving an invalid USB descriptor. (CVE-2016-2384)\n\n - The snd_timer_user_params function in sound/core/timer.c in the Linux kernel through 4.6 does not initialize a certain data structure, which allows local users to obtain sensitive information from kernel stack memory via crafted use of the ALSA timer interface. (CVE-2016-4569)\n\n - sound/core/timer.c in the Linux kernel through 4.6 does not initialize certain r1 data structures, which allows local users to obtain sensitive information from kernel stack memory via crafted use of the ALSA timer interface, related to the (1) snd_timer_user_ccallback and (2) snd_timer_user_tinterrupt functions.\n (CVE-2016-4578)\n\n - arch/powerpc/kvm/book3s_hv_rmhandlers.S in the Linux kernel through 4.7 on PowerPC platforms, when CONFIG_KVM_BOOK3S_64_HV is enabled, allows guest OS users to cause a denial of service (host OS infinite loop) by making a H_CEDE hypercall during the existence of a suspended transaction. (CVE-2016-5412)\n\n - drivers/infiniband/ulp/srpt/ib_srpt.c in the Linux kernel before 4.5.1 allows local users to cause a denial of service (NULL pointer dereference and system crash) by using an ABORT_TASK command to abort a device write operation. (CVE-2016-6327)\n\n - Race condition in the ioctl_send_fib function in drivers/scsi/aacraid/commctrl.c in the Linux kernel through 4.7 allows local users to cause a denial of service (out-of-bounds access or system crash) by changing a certain size value, aka a double fetch vulnerability. (CVE-2016-6480)\n\n - fs/nfs/nfs4proc.c in the NFS client in the Linux kernel before 4.2.2 does not properly initialize memory for migration recovery operations, which allows remote NFS servers to cause a denial of service (NULL pointer dereference and panic) via crafted network traffic. (CVE-2015-8746)\n\n - drivers/infiniband/hw/cxgb3/iwch_cm.c in the Linux kernel before 4.5 does not properly identify error conditions, which allows remote attackers to execute arbitrary code or cause a denial of service (use- after-free) via crafted packets. (CVE-2015-8812)\n\n - The trace_writeback_dirty_page implementation in include/trace/events/writeback.h in the Linux kernel before 4.4 improperly interacts with mm/migrate.c, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by triggering a certain page move. (CVE-2016-3070)\n\n - The Linux kernel, as used in Red Hat Enterprise Linux 7.2 and Red Hat Enterprise MRG 2 and when booted with UEFI Secure Boot enabled, allows local users to bypass intended Secure Boot restrictions and execute untrusted code by appending ACPI tables to the initrd. (CVE-2016-3699)\n\n - The IPv6 stack in the Linux kernel before 4.3.3 mishandles options data, which allows local users to gain privileges or cause a denial of service (use-after-free and system crash) via a crafted sendmsg system call.

"description": "According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :\n\n - The kernel package contains the Linux kernel (vmlinuz), the core of any Linux operating system. The kernel handles the basic functions of the operating system:\n memory allocation, process allocation, device input and output, etc.Security Fix(es):** DISPUTED ** Multiple integer overflows in the lzo1x_decompress_safe function in lib/lzo/lzo1x_decompress_safe.c in the LZO decompressor in the Linux kernel before 3.15.2 allow context-dependent attackers to cause a denial of service (memory corruption) via a crafted Literal Run.\n NOTE: the author of the LZO algorithms says 'the Linux kernel is *not* affected media hype.'(CVE-2014-4608)A certain backport in the TCP Fast Open implementation for the Linux kernel before 3.18 does not properly maintain a count value, which allow local users to cause a denial of service (system crash) via the Fast Open feature, as demonstrated by visiting the chrome://flags/#enable-tcp-fast-open URL when using certain 3.10.x through 3.16.x kernel builds, including longterm-maintenance releases and ckt (aka Canonical Kernel Team) builds.(CVE-2015-3332)An elevation of privilege vulnerability in the kernel scsi driver.\n Product: Android. Versions: Android kernel. Android ID A-65023233.(CVE-2017-13168)An issue was discovered in drivers/i2c/i2c-core-smbus.c in the Linux kernel before 4.14.15. There is an out of bounds write in the function i2c_smbus_xfer_emulated.(CVE-2017-18551)An issue was discovered in net/ipv6/ip6mr.c in the Linux kernel before 4.11. By setting a specific socket option, an attacker can control a pointer in kernel land and cause an inet_csk_listen_stop general protection fault, or potentially execute arbitrary code under certain circumstances. The issue can be triggered as root (e.g., inside a default LXC container or with the CAP_NET_ADMIN capability) or after namespace unsharing. This occurs because sk_type and protocol are not checked in the appropriate part of the ip6_mroute_* functions. NOTE: this affects Linux distributions that use 4.9.x longterm kernels before 4.9.187.(CVE-2017-18509)An issue was discovered in the Linux kernel before 4.14.11. A double free may be caused by the function allocate_trace_buffer in the file kernel/trace/trace.c.(CVE-2017-18595)An issue was discovered in the Linux kernel through 4.17.10. There is a NULL pointer dereference and panic in hfsplus_lookup() in fs/hfsplus/dir.c when opening a file (that is purportedly a hard link) in an hfs+ filesystem that has malformed catalog data, and is mounted read-only without a metadata directory.(CVE-2018-14617)An issue was discovered in write_tpt_entry in drivers/infiniband/hw/cxgb4/mem.c in the Linux kernel through 5.3.2. The cxgb4 driver is directly calling dma_map_single (a DMA function) from a stack variable. This could allow an attacker to trigger a Denial of Service, exploitable if this driver is used on an architecture for which this stack/DMA interaction has security relevance.(CVE-2019-17075)Double free vulnerability in the snd_usbmidi_create function in sound/usb/midi.c in the Linux kernel before 4.5 allows physically proximate attackers to cause a denial of service (panic) or possibly have unspecified other impact via vectors involving an invalid USB descriptor.(CVE-2016-2384)fsamespace.c in the Linux kernel through 3.16.1 does not properly restrict clearing MNT_NODEV, MNT_NOSUID, and MNT_NOEXEC and changing MNT_ATIME_MASK during a remount of a bind mount, which allows local users to gain privileges, interfere with backups and auditing on systems that had atime enabled, or cause a denial of service (excessive filesystem updating) on systems that had atime disabled via a 'mount -o remount' command within a user namespace.(CVE-2014-5207)fs/overlayfs/dir.c in the OverlayFS filesystem implementation in the Linux kernel before 4.6 does not properly verify the upper dentry before proceeding with unlink and rename system-call processing, which allows local users to cause a denial of service (system crash) via a rename system call that specifies a self-hardlink.(CVE-2016-6197)In the Linux kernel before 4.1.4, a buffer overflow occurs when checking userspace params in drivers/media/dvb-frontends/cx24116.c. The maximum size for a DiSEqC command is 6, according to the userspace API. However, the code allows larger values such as 23.(CVE-2015-9289)In the Linux kernel through 5.3.2, cfg80211_mgd_wext_giwessid in net/wireless/wext-sme.c does not reject a long SSID IE, leading to a Buffer Overflow.(CVE-2019-17133)Insufficient access control in the Intel(R) PROSet/Wireless WiFi Software driver before version 21.10 may allow an unauthenticated user to potentially enable denial of service via adjacent access.(CVE-2019-0136)Linux distributions that have not patched their long-term kernels with https://git.kernel.org/linus/a87938b2e246b81b4fb713edb3 71a9fa3c5c3c86 (committed on April 14, 2015). This kernel vulnerability was fixed in April 2015 by commit a87938b2e246b81b4fb713edb371a9fa3c5c3c86 (backported to Linux 3.10.77 in May 2015), but it was not recognized as a security threat. With CONFIG_ARCH_BINFMT_ELF_RANDOMIZE_PIE enabled, and a normal top-down address allocation strategy, load_elf_binary() will attempt to map a PIE binary into an address range immediately below mm->mmap_base.\n Unfortunately, load_elf_ binary() does not take account of the need to allocate sufficient space for the entire binary which means that, while the first PT_LOAD segment is mapped below mm->mmap_base, the subsequent PT_LOAD segment(s) end up being mapped above mm->mmap_base into the are that is supposed to be the 'gap' between the stack and the binary.(CVE-2017-1000253)Race condition in the sclp_ctl_ioctl_sccb function in drivers/s390/char/sclp_ctl.c in the Linux kernel before 4.6 allows local users to obtain sensitive information from kernel memory by changing a certain length value, aka a 'double fetch' vulnerability.(CVE-2016-6130)rtl_p2p_noa_ie in drivers et/wireless/realtek/rtlwifi/ps.c in the Linux kernel through 5.3.6 lacks a certain upper-bound check, leading to a buffer overflow.(CVE-2019-17666)sound/core/timer.c in the Linux kernel through 4.6 does not initialize certain r1 data structures, which allows local users to obtain sensitive information from kernel stack memory via crafted use of the ALSA timer interface, related to the (1) snd_timer_user_ccallback and (2) snd_timer_user_tinterrupt functions.(CVE-2016-4578)Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis.(CVE-2017-5753)The acm_probe function in drivers/usb/class/cdc-acm.c in the Linux kernel before 4.5.1 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a USB device without both a control and a data endpoint descriptor.(CVE-2016-3138)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)The ati_remote2_probe function in drivers/input/misc/ati_remote2.c in the Linux kernel before 4.5.1 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted endpoints value in a USB device descriptor.(CVE-2016-2185)The create_fixed_stream_quirk function in sound/usb/quirks.c in the snd-usb-audio driver in the Linux kernel before 4.5.1 allows physically proximate attackers to cause a denial of service (NULL pointer dereference or double free, and system crash) via a crafted endpoints value in a USB device descriptor.(CVE-2016-2184)The digi_port_init function in drivers/usb/serial/digi_acceleport.c in the Linux kernel before 4.5.1 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted endpoints value in a USB device descriptor.(CVE-2016-3140)The do_remount function in fsamespace.c in the Linux kernel through 3.16.1 does not maintain the MNT_LOCK_READONLY bit across a remount of a bind mount, which allows local users to bypass an intended read-only restriction and defeat certain sandbox protection mechanisms via a 'mount -o remount' command within a user namespace.(CVE-2014-5206)The gtco_probe function in drivers/input/tablet/gtco.c in the Linux kernel through 4.5.2 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted endpoints value in a USB device descriptor.(CVE-2016-2187)The hub_activate function in drivers/usb/core/hub.c in the Linux kernel before 4.3.5 does not properly maintain a hub-interface data structure, which allows physically proximate attackers to cause a denial of service (invalid memory access and system crash) or possibly have unspecified other impact by unplugging a USB hub device.(CVE-2015-8816)The ims_pcu_parse_cdc_data function in drivers/input/misc/ims-pcu.c in the Linux kernel before 4.5.1 allows physically proximate attackers to cause a denial of service (system crash) via a USB device without both a master and a slave interface.(CVE-2016-3689)The Linux Kernel running on AMD64 systems will sometimes map the contents of PIE executable, the heap or ld.so to where the stack is mapped allowing attackers to more easily manipulate the stack.

unspecified other impact via a crafted application that leverages a race condition between keyctl_revoke and keyctl_read calls (bnc#958951).\n\n - CVE-2015-7566: A malicious USB device could cause kernel crashes in the visor device driver (bnc#961512).\n\n - CVE-2015-7799: The slhc_init function in drivers/net/slip/slhc.c in the Linux kernel did not ensure that certain slot numbers are valid, which allowed local users to cause a denial of service (NULL pointer dereference and system crash) via a crafted PPPIOCSMAXCID ioctl call (bnc#949936).\n\n - CVE-2015-8215: net/ipv6/addrconf.c in the IPv6 stack in the Linux kernel did not validate attempted changes to the MTU value, which allowed context-dependent attackers to cause a denial of service (packet loss) via a value that is (1) smaller than the minimum compliant value or (2) larger than the MTU of an interface, as demonstrated by a Router Advertisement (RA) message that is not validated by a daemon, a different vulnerability than CVE-2015-0272. NOTE: the scope of CVE-2015-0272 is limited to the NetworkManager product (bnc#955354).\n\n - CVE-2015-8539: The KEYS subsystem in the Linux kernel allowed local users to gain privileges or cause a denial of service (BUG) via crafted keyctl commands that negatively instantiate a key, related to security/keys/encrypted-keys/encrypted.c, security/keys/trusted.c, and security/keys/user_defined.c (bnc#958463).\n\n - CVE-2015-8543: The networking implementation in the Linux kernel did not validate protocol identifiers for certain protocol families, which allowed local users to cause a denial of service (NULL function pointer dereference and system crash) or possibly gain privileges by leveraging CLONE_NEWUSER support to execute a crafted SOCK_RAW application (bnc#958886).\n\n - CVE-2015-8550: Optimizations introduced by the compiler could have lead to double fetch vulnerabilities, potentially possibly leading to arbitrary code execution in backend (bsc#957988). (bsc#957988 XSA-155).\n\n - CVE-2015-8551: The PCI backend driver in Xen, when running on an x86 system and using Linux as the driver domain, allowed local guest administrators to hit BUG conditions and cause a denial of service (NULL pointer dereference and host OS crash) by leveraging a system with access to a passed-through MSI or MSI-X capable physical PCI device and a crafted sequence of XEN_PCI_OP_* operations, aka 'Linux pciback missing sanity checks (bnc#957990).\n\n - CVE-2015-8552: The PCI backend driver in Xen, when running on an x86 system and using Linux as the driver domain, allowed local guest administrators to generate a continuous stream of WARN messages and cause a denial of service (disk consumption) by leveraging a system with access to a passed-through MSI or MSI-X capable physical PCI device and XEN_PCI_OP_enable_msi operations, aka 'Linux pciback missing sanity checks (bnc#957990).\n\n - CVE-2015-8569: The (1) pptp_bind and (2) pptp_connect functions in drivers/net/ppp/pptp.c in the Linux kernel do not verify an address length, which allowed local users to obtain sensitive information from kernel memory and bypass the KASLR protection mechanism via a crafted application (bnc#959190).\n\n - CVE-2015-8575: The sco_sock_bind function in net/bluetooth/sco.c in the Linux kernel did not verify an address length, which allowed local users to obtain sensitive information from kernel memory and bypass the KASLR protection mechanism via a crafted application (bnc#959399).\n\n - CVE-2015-8767: net/sctp/sm_sideeffect.c in the Linux kernel did not properly manage the relationship between a lock and a socket, which allowed local users to cause a denial of service (deadlock) via a crafted sctp_accept call (bnc#961509).\n\n - CVE-2015-8785: The fuse_fill_write_pages function in fs/fuse/file.c in the Linux kernel allowed local users to cause a denial of service (infinite loop) via a writev system call that triggers a zero length for the first segment of an iov (bnc#963765).\n\n - CVE-2015-8812: A flaw was found in the CXGB3 kernel driver when the network was considered congested. The kernel would incorrectly misinterpret the congestion as an error condition and incorrectly free/clean up the skb. When the device would then send the skb's queued, these structures would be referenced and may panic the system or allow an attacker to escalate privileges in a use-after-free scenario.(bsc#966437).\n\n - CVE-2015-8816: A malicious USB device could cause kernel crashes in the in hub_activate() function (bnc#968010).\
