The SUSE Linux Enterprise 11 SP 3 kernel was updated to fix two security
issues.
The following security bugs were fixed:
- CVE-2016-9576: A use-after-free vulnerability in the SCSI generic driver
allows users with write access to /dev/sg* or /dev/bsg* to elevate their
privileges (bsc#1013604).
- CVE-2016-9794: A use-after-free vulnerability in the ALSA pcm layer
allowed local users to cause a denial of service, memory corruption or
possibly even to elevate their privileges (bsc#1013533).

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.

Use-after-free vulnerability in the\n __sys_recvmmsg function in net/socket.c in the Linux kernel allowed remote attackers to execute arbitrary code via vectors involving a recvmmsg system call that is mishandled during error processing (bnc#1003077).\n\n - CVE-2017-5551: tmpfs: Fixed a bug that could have allowed users to set setgid bits on files they don't down (bsc#1021258).\n\n - CVE-2016-10147: crypto/mcryptd.c in the Linux kernel allowed local users to cause a denial of service (NULL pointer dereference and system crash) by using an AF_ALG socket with an incompatible algorithm, as demonstrated by mcryptd(md5) (bnc#1020381).\n\n - CVE-2016-10088: The sg implementation in the Linux kernel did not properly restrict write operations in situations where the KERNEL_DS

block/bsg.c and drivers/scsi/sg.c.\n NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-9576 (bnc#1017710).\n\n - CVE-2016-7917: The nfnetlink_rcv_batch function in net/netfilter/nfnetlink.c in the Linux kernel did not check whether a batch message's length field is large enough, which allowed local users to obtain sensitive information from kernel memory or cause a denial of service (infinite loop or out-of-bounds read) by leveraging the CAP_NET_ADMIN capability (bnc#1010444).\n\n - CVE-2016-8645: The TCP stack in the Linux kernel mishandled skb truncation, which allowed local users to cause a denial of service (system crash) via a crafted application that made sendto system calls, related to net/ipv4/tcp_ipv4.c and net/ipv6/tcp_ipv6.c

(bsc#1020214).\n\n - clk: xgene: Do not call __pa on ioremaped address\n (bsc#1019660).\n\n - kABI workaround for 4.1.37 mount changes\n (stable-4.1.37).\n\n - kABI: reintroduce sk_filter (bsc#1009969).\n\n - kabi/severities: Ignore inode_change_ok change It's\n renamed in 4.1.37 to setattr_prepare()\n\n - mpi: Fix NULL ptr dereference in mpi_powm() [ver #3]\n (bsc#1011820).\n\n - net: introduce __sock_queue_rcv_skb() function\n (bsc#1009969).\n\n - netback: correct array index (bsc#983348).\n\n - netfront: do not truncate grant references.\n\n - netfront: use correct linear area after linearizing an\n skb (bsc#1007886).\n\n - reiserfs: fix race in prealloc discard (bsc#987576).\n\n - rose: limit sk_filter trim to payload (bsc#1009969).\n\n - scsi: bfa: Increase requested firmware version to\n 3.2.5.1 (bsc#1013273).\n\n - xenbus: correctly signal errors from\n xenstored_local_init() (luckily none so far).\n\n - xenbus: do not invoke ->is_ready() for most device\n states (bsc#987333).\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://bugzilla.opensuse.org/show_bug.cgi?id=1003077\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n

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 attacker with\nphysical access to the system could use this flaw to escalate their\nprivileges. (CVE-2016-2384, Low)\n\nThe CVE-2016-7042 issue was discovered by Ondrej Kozina (Red Hat) and\nthe CVE-2016-7097 issue was discovered by Andreas Gruenbacher (Red\nHat) and Jan Kara

(CVE-2016-2069)\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 - 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 - The proc_keys_show function in security/keys/proc.c in the Linux kernel through 4.8.2, when the GNU Compiler Collection (gcc) stack protector is enabled, uses an incorrect buffer size for certain timeout data, which allows local users to cause a denial of service (stack memory corruption and panic) by reading the /proc/keys file. (CVE-2016-7042)\n\n - The blk_rq_map_user_iov function in block/blk-map.c in the Linux kernel before 4.8.14 does not properly restrict the type of iterator, 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.\n (CVE-2016-9576)\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-2016-7097)\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.

(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.

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.

Applications using the\n splice() and tcp_splice_read() functionality can allow\n a remote attacker to force the kernel to enter a\n condition in which it can loop indefinitely.\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\n a fragmentation-based attack against legacy IPv6 nodes\n that do not implement RFC6946.\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.\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.\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().\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\n doesn't clear the setgid bit in a similar way. This\n could allow a local user to gain group privileges via\n certain setgid applications.\n\n - It was found that when the gcc stack protector was\n enabled, reading the /proc/keys file could cause a\n panic 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\n - A race condition flaw was found in the ioctl_send_fib()\n function in the Linux kernel's aacraid implementation.\n A local attacker could use this flaw to cause a denial\n of service (out-of-bounds access or system crash) by\n changing a certain size value.\n\n - When creating audit records for parameters to executed\n children processes, an attacker can convince the Linux\n kernel audit subsystem can create corrupt records which\n may allow an attacker to misrepresent or evade logging\n of executing commands.\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\n switching to a process that uses the paging structure\n in question. A local user could use a thread running\n with a stale cached virtual->physical translation to\n potentially escalate their privileges if the\n translation in question were writable and the physical\n page got reused for something critical (for example, a\n page table).\n\n - A flaw was found in the USB-MIDI Linux kernel driver: a\n double-free error could be triggered for the 'umidi'\n 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:\"expl
