Summary

The mq_notify function in the Linux kernel through 4.11.9 does not set the sock pointer to NULL upon entry into the retry logic. During a user-space close of a Netlink socket, it allows attackers to cause a denial of service (use-after-free) or possibly have unspecified other impact.

"An update for kernel-rt is now available for Red Hat Enterprise MRG 2.

Red Hat Product Security has rated this update as having a security
impact of Important. 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.

The kernel-rt packages provide the Real Time Linux Kernel, which
enables fine-tuning for systems with extremely high determinism
requirements.

Security Fix(es) :

* Out-of-bounds kernel heap access vulnerability was found in xfrm,
kernel's IP framework for transforming packets. An error dealing with
netlink messages from an unprivileged user leads to arbitrary
read/write and privilege escalation. (CVE-2017-7184, Important)

* A race condition issue leading to a use-after-free flaw was found in
the way the raw packet sockets are implemented in the Linux kernel
networking subsystem handling synchronization. A local user able to
open a raw packet socket (requires the CAP_NET_RAW capability) could
use this flaw to elevate their privileges on the system.
(CVE-2017-1000111, Important)

* An exploitable memory corruption flaw was found in the Linux kernel.
The append path can be erroneously switched from UFO to non-UFO in
ip_ufo_append_data() when building an UFO packet with MSG_MORE option.
If unprivileged user namespaces are available, this flaw can be
exploited to gain root privileges. (CVE-2017-1000112, Important)

* Kernel memory corruption due to a buffer overflow was found in
brcmf_cfg80211_mgmt_tx() function in Linux kernels from v3.9-rc1 to
v4.13-rc1. The vulnerability can be triggered by sending a crafted
NL80211_CMD_FRAME packet via netlink. This flaw is unlikely to be
triggered remotely as certain userspace code is needed for this. An
unprivileged local user could use this flaw to induce kernel memory
corruption on the system, leading to a crash. Due to the nature of the
flaw, privilege escalation cannot be fully ruled out, although it is
unlikely. (CVE-2017-7541, Moderate)

* An integer overflow vulnerability in ip6_find_1stfragopt() function
was found. A local attacker that has privileges (of CAP_NET_RAW) to
open raw socket can cause an infinite loop inside the
ip6_find_1stfragopt() function. (CVE-2017-7542, Moderate)

* A kernel data leak due to an out-of-bound read was found in the
Linux kernel in inet_diag_msg_sctp{,l}addr_fill() and
sctp_get_sctp_info() functions present since version 4.7-rc1 through
version 4.13. A data leak happens when these functions fill in
sockaddr data structures used to export socket's diagnostic
information. As a result, up to 100 bytes of the slab data could be
leaked to a userspace. (CVE-2017-7558, Moderate)

* The mq_notify function in the Linux kernel through 4.11.9 does not
set the sock pointer to NULL upon entry into the retry logic. During a
user-space close of a Netlink socket, it allows attackers to possibly
cause a situation where a value may be used after being freed
(use-after-free) which may lead to memory corruption or other
unspecified other impact. (CVE-2017-11176, Moderate)

* A divide-by-zero vulnerability was found in the __tcp_select_window
function in the Linux kernel. This can result in a kernel panic
causing a local denial of service. (CVE-2017-14106, Moderate)

* A flaw was found where the XFS filesystem code mishandles a
user-settable inode flag in the Linux kernel prior to 4.14-rc1. This
can cause a local denial of service via a kernel panic.
(CVE-2017-14340, Moderate)

Red Hat would like to thank Chaitin Security Research Lab for
reporting CVE-2017-7184; Willem de Bruijn for reporting
CVE-2017-1000111; and Andrey Konovalov for reporting CVE-2017-1000112.
The CVE-2017-7558 issue was discovered by Stefano Brivio (Red Hat) and
the CVE-2017-14340 issue was discovered by Dave Chinner (Red Hat).

Bug Fix(es) :

* kernel-rt packages have been upgraded to the 3.10.0-693.5.2 source
tree, which provides number of bug fixes over the previous version.

    descriptionAn update for kernel is now available for Red Hat Enterprise Linux 6. Red Hat Product Security has rated this update as having a security impact of Important. 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. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es) : * An integer overflow vulnerability in ip6_find_1stfragopt() function was found. A local attacker that has privileges (of CAP_NET_RAW) to open raw socket can cause an infinite loop inside the ip6_find_1stfragopt() function. (CVE-2017-7542, Moderate) * The IPv6 fragmentation implementation in the Linux kernel does not consider that the nexthdr field may be associated with an invalid option, which allows local users to cause a denial of service (out-of-bounds read and BUG) or possibly have unspecified other impact via crafted socket and send system calls. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely. (CVE-2017-9074, Moderate) * A use-after-free flaw was found in the Netlink functionality of the Linux kernel networking subsystem. Due to the insufficient cleanup in the mq_notify function, a local attacker could potentially use this flaw to escalate their privileges on the system. (CVE-2017-11176, Moderate) Bug Fix(es) : * Previously, the default timeout and retry settings in the VMBus driver were insufficient in some cases, for example when a Hyper-V host was under a significant load. Consequently, in Windows Server 2016, Hyper-V Server 2016, and Windows Azure Platform, when running a Red Hat Enterprise Linux Guest on the Hyper-V hypervisor, the guest failed to boot or booted with certain Hyper-V devices missing. This update alters the timeout and retry settings in VMBus, and Red Hat Enterprise Linux guests now boot as expected under the described conditions. (BZ#1506145) * Previously, an incorrect external declaration in the be2iscsi driver caused a kernel panic when using the systool utility. With this update, the external declaration in be2iscsi has been fixed, and the kernel no longer panics when using systool. (BZ#1507512) * Under high usage of the NFSD file system and memory pressure, if many tasks in the Linux kernel attempted to obtain the global spinlock to clean the Duplicate Reply Cache (DRC), these tasks stayed in an active wait in the nfsd_reply_cache_shrink() function for up to 99% of time. Consequently, a high load average occurred. This update fixes the bug by separating the DRC in several parts, each with an independent spinlock. As a result, the load and CPU utilization is no longer excessive under the described circumstances. (BZ#1509876) * When attempting to attach multiple SCSI devices simultaneously, Red Hat Enterprise Linux 6.9 on IBM z Systems sometimes became unresponsive.

    descriptionSecurity Fix(es) : - An integer overflow vulnerability in ip6_find_1stfragopt() function was found. A local attacker that has privileges (of CAP_NET_RAW) to open raw socket can cause an infinite loop inside the ip6_find_1stfragopt() function. (CVE-2017-7542, Moderate) - The IPv6 fragmentation implementation in the Linux kernel does not consider that the nexthdr field may be associated with an invalid option, which allows local users to cause a denial of service (out-of-bounds read and BUG) or possibly have unspecified other impact via crafted socket and send system calls. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely. (CVE-2017-9074, Moderate) - A use-after-free flaw was found in the Netlink functionality of the Linux kernel networking subsystem. Due to the insufficient cleanup in the mq_notify function, a local attacker could potentially use this flaw to escalate their privileges on the system. (CVE-2017-11176, Moderate) Bug Fix(es) : - Previously, the default timeout and retry settings in the VMBus driver were insufficient in some cases, for example when a Hyper-V host was under a significant load. Consequently, in Windows Server 2016, Hyper-V Server 2016, and Windows Azure Platform, when running a Scientific Linux Guest on the Hyper-V hypervisor, the guest failed to boot or booted with certain Hyper-V devices missing. This update alters the timeout and retry settings in VMBus, and Scientific Linux guests now boot as expected under the described conditions. - Previously, an incorrect external declaration in the be2iscsi driver caused a kernel panic when using the systool utility. With this update, the external declaration in be2iscsi has been fixed, and the kernel no longer panics when using systool. - Under high usage of the NFSD file system and memory pressure, if many tasks in the Linux kernel attempted to obtain the global spinlock to clean the Duplicate Reply Cache (DRC), these tasks stayed in an active wait in the nfsd_reply_cache_shrink() function for up to 99% of time. Consequently, a high load average occurred. This update fixes the bug by separating the DRC in several parts, each with an independent spinlock. As a result, the load and CPU utilization is no longer excessive under the described circumstances. - When attempting to attach multiple SCSI devices simultaneously, Scientific Linux 6.9 on IBM z Systems sometimes became unresponsive. This update fixes the zfcp device driver, and attaching multiple SCSI devices simultaneously now works as expected in the described scenario. - On IBM z Systems, the tiqdio_call_inq_handlers() function in the Linux kernel incorrectly cleared the device state change indicator (DSCI) for the af_iucv devices using the HiperSockets transport with multiple input queues. Consequently, queue stalls on such devices occasionally occurred. With this update, tiqdio_call_inq_handlers() has been fixed to clear the DSCI only once, prior to scanning the queues. As a result, queue stalls for af_iucv devices using the HiperSockets transport no longer occur under the described circumstances. - Previously, small data chunks caused the Stream Control Transmission Protocol (SCTP) to account the receiver_window (rwnd) values incorrectly when recovering from a

CVE-2017-10661 Dmitry Vyukov of Google reported that the timerfd facility does not properly handle certain concurrent operations on a single file descriptor. This allows a local attacker to cause a denial of service or potentially to execute arbitrary code. CVE-2017-10911 / XSA-216 Anthony Perard of Citrix discovered an information leak flaw in Xen blkif response handling, allowing a malicious unprivileged guest to obtain sensitive information from the host or other guests. CVE-2017-11176 It was discovered that the mq_notify() function does not set the sock pointer to NULL upon entry into the retry logic. An attacker can take advantage of this flaw during a userspace close of a Netlink socket to cause a denial of service or potentially cause other impact. CVE-2017-11600 bo Zhang reported that the xfrm subsystem does not properly validate one of the parameters to a netlink message. Local users with the CAP_NET_ADMIN capability can use this to cause a denial of service or potentially to execute arbitrary code. CVE-2017-12134 / #866511 / XSA-229 Jan H. Sch&ouml;nherr of Amazon discovered that when Linux is running in a Xen PV domain on an x86 system, it may incorrectly merge block I/O requests. A buggy or malicious guest may trigger this bug in dom0 or a PV driver domain, causing a denial of service or potentially execution of arbitrary code. This issue can be mitigated by disabling merges on the underlying back-end block devices, e.g.: echo 2 > /sys/block/nvme0n1/queue/nomerges CVE-2017-12153 bo Zhang reported that the cfg80211 (wifi) subsystem does not properly validate the parameters to a netlink message. Local users with the CAP_NET_ADMIN capability on a system with a wifi device can use this to cause a denial of service. CVE-2017-12154 Jim Mattson of Google reported that the KVM implementation for Intel x86 processors did not correctly handle certain nested hypervisor configurations. A malicious guest (or nested guest in a suitable L1 hypervisor) could use this for denial of service. CVE-2017-14106 Andrey Konovalov of Google reported that a specific sequence of operations on a TCP socket could lead to division by zero. A local user could use this for denial of service. CVE-2017-14140 Otto Ebeling reported that the move_pages() system call permitted users to discover the memory layout of a set-UID process running under their real user-ID. This made it easier for local users to exploit vulnerabilities in programs installed with the set-UID permission bit set. CVE-2017-14156

    descriptionAccording to the versions of the parallels-server-bm-release / vzkernel / etc packages installed, the Virtuozzo installation on the remote host is affected by the following vulnerabilities : - An integer overflow vulnerability in ip6_find_1stfragopt() function was found. A local attacker that has privileges (of CAP_NET_RAW) to open raw socket can cause an infinite loop inside the ip6_find_1stfragopt() function. - Race condition in fs/timerfd.c in the Linux kernel before 4.10.15 allows local users to gain privileges or cause a denial of service (list corruption or use-after-free) via simultaneous file-descriptor operations that leverage improper might_cancel queueing. - A race condition issue leading to a use-after-free flaw was found in the way the raw packet sockets are implemented in the Linux kernel networking subsystem handling synchronization. A local user able to open a raw packet socket (requires the CAP_NET_RAW capability) could use this flaw to elevate their privileges on the system. - Andrey Konovalov discovered a race condition in the UDP Fragmentation Offload (UFO) code in the Linux kernel. A local attacker could use this to cause a denial of service or execute arbitrary code. - Kernel memory corruption due to a buffer overflow was found in brcmf_cfg80211_mgmt_tx() function in Linux kernels from v3.9-rc1 to v4.13-rc1. The vulnerability can be triggered by sending a crafted NL80211_CMD_FRAME packet via netlink. This flaw is unlikely to be triggered remotely as certain userspace code is needed for this. An unprivileged local user could use this flaw to induce kernel memory corruption on the system, leading to a crash. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely. - The mq_notify function in the Linux kernel through 4.11.9 does not set the sock pointer to NULL upon entry into the retry logic. During a user-space close of a Netlink socket, it allows attackers to possibly cause a situation where a value may be used after being freed (use after free) which may lead to memory corruption or other unspecified other impact. - The tcp_disconnect function in net/ipv4/tcp.c in the Linux kernel before 4.12 allows local users to cause a denial of service (__tcp_select_window divide-by-zero error and system crash) by triggering a disconnect within a certain tcp_recvmsg code path. Note that Tenable Network Security has extracted the preceding description block directly from the Virtuozzo security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    descriptionFrom Red Hat Security Advisory 2018:0169 : An update for kernel is now available for Red Hat Enterprise Linux 6. Red Hat Product Security has rated this update as having a security impact of Important. 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. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es) : * An integer overflow vulnerability in ip6_find_1stfragopt() function was found. A local attacker that has privileges (of CAP_NET_RAW) to open raw socket can cause an infinite loop inside the ip6_find_1stfragopt() function. (CVE-2017-7542, Moderate) * The IPv6 fragmentation implementation in the Linux kernel does not consider that the nexthdr field may be associated with an invalid option, which allows local users to cause a denial of service (out-of-bounds read and BUG) or possibly have unspecified other impact via crafted socket and send system calls. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely. (CVE-2017-9074, Moderate) * A use-after-free flaw was found in the Netlink functionality of the Linux kernel networking subsystem. Due to the insufficient cleanup in the mq_notify function, a local attacker could potentially use this flaw to escalate their privileges on the system. (CVE-2017-11176, Moderate) Bug Fix(es) : * Previously, the default timeout and retry settings in the VMBus driver were insufficient in some cases, for example when a Hyper-V host was under a significant load. Consequently, in Windows Server 2016, Hyper-V Server 2016, and Windows Azure Platform, when running a Red Hat Enterprise Linux Guest on the Hyper-V hypervisor, the guest failed to boot or booted with certain Hyper-V devices missing. This update alters the timeout and retry settings in VMBus, and Red Hat Enterprise Linux guests now boot as expected under the described conditions. (BZ#1506145) * Previously, an incorrect external declaration in the be2iscsi driver caused a kernel panic when using the systool utility. With this update, the external declaration in be2iscsi has been fixed, and the kernel no longer panics when using systool. (BZ#1507512) * Under high usage of the NFSD file system and memory pressure, if many tasks in the Linux kernel attempted to obtain the global spinlock to clean the Duplicate Reply Cache (DRC), these tasks stayed in an active wait in the nfsd_reply_cache_shrink() function for up to 99% of time. Consequently, a high load average occurred. This update fixes the bug by separating the DRC in several parts, each with an independent spinlock. As a result, the load and CPU utilization is no longer excessive under the described circumstances. (BZ#1509876) * When attempting to attach multiple SCSI devices simultaneously, Red Hat Enterprise Linux 6.9 on IBM z Systems sometimes became unresponsive. This update fixes the zfcp device driver, and attaching multiple SCSI devices simultaneously now works as expected in the described scenario. (BZ# 1512425) * On IBM z Systems, the tiqdio_call_inq_handlers() function in the Linux kernel incorrectly cleared the device state change indicator (DSCI) for the af_iucv devices using the HiperSockets transport with multiple input queues. Consequently, queue stalls on such devices occasionally occurred. With this update, tiqdio_call_inq_handlers() has been fixed to clear the DSCI only once, prior to scanning the queues. As a result, queue stalls for af_iucv devices using the HiperSockets transport no longer occur under the described circumstances. (BZ#1513314) * Previously, small data chunks caused the Stream Control Transmission Protocol (SCTP) to account the receiver_window (rwnd) values incorrectly when recovering from a 'zero-window situation'. As a consequence, window updates were not sent to the peer, and an artificial growth of rwnd could lead to packet drops. This update properly accounts such small data chunks and ignores the rwnd pressure values when reopening a window. As a result, window updates are now sent, and the announced rwnd reflects better the real state of the receive buffer. (BZ#1514443) This plugin has been deprecated because Oracle has changed their mind and decided that ELSA-2018-0169 does not fix any security problems.

    descriptionThe SUSE Linux Enterprise 12 GA LTS kernel was updated to receive various security and bugfixes. The following security bugs were fixed : - CVE-2017-15649: net/packet/af_packet.c in the Linux kernel allowed local users to gain privileges via crafted system calls that trigger mishandling of packet_fanout data structures, because of a race condition (involving fanout_add and packet_do_bind) that leads to a use-after-free, a different vulnerability than CVE-2017-6346 (bnc#1064388). - CVE-2015-9004: kernel/events/core.c in the Linux kernel mishandled counter grouping, which allowed local users to gain privileges via a crafted application, related to the perf_pmu_register and perf_event_open functions (bnc#1037306). - CVE-2016-10229: udp.c in the Linux kernel allowed 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 (bnc#1032268). - CVE-2016-9604: The handling of keyrings starting with

    descriptionThe SUSE Linux Enterprise 12 SP1 LTS kernel was updated to receive various security and bugfixes. The following security bugs were fixed : - CVE-2017-15649: net/packet/af_packet.c in the Linux kernel allowed local users to gain privileges via crafted system calls that trigger mishandling of packet_fanout data structures, because of a race condition (involving fanout_add and packet_do_bind) that leads to a use-after-free, a different vulnerability than CVE-2017-6346 (bnc#1064388). - CVE-2017-13080: Wi-Fi Protected Access (WPA and WPA2) allowed reinstallation of the Group Temporal Key (GTK) during the group key handshake, allowing an attacker within radio range to replay frames from access points to clients (bnc#1063667). - CVE-2017-15274: security/keys/keyctl.c in the Linux kernel did not consider the case of a NULL payload in conjunction with a nonzero length value, which allowed local users to cause a denial of service (NULL pointer dereference and OOPS) via a crafted add_key or keyctl system call, a different vulnerability than CVE-2017-12192 (bnc#1045327). - CVE-2017-15265: Use-after-free vulnerability in the Linux kernel allowed local users to have unspecified impact via vectors related to /dev/snd/seq (bnc#1062520). - CVE-2017-1000365: The Linux Kernel imposes a size restriction on the arguments and environmental strings passed through RLIMIT_STACK/RLIM_INFINITY (1/4 of the size), but did not take the argument and environment pointers into account, which allowed attackers to bypass this limitation. (bnc#1039354). - CVE-2017-12153: A security flaw was discovered in the nl80211_set_rekey_data() function in net/wireless/nl80211.c in the Linux kernel This function did not check whether the required attributes are present in a Netlink request. This request can be issued by a user with the CAP_NET_ADMIN capability and may result in a NULL pointer dereference and system crash (bnc#1058410). - CVE-2017-12154: The prepare_vmcs02 function in arch/x86/kvm/vmx.c in the Linux kernel did not ensure that the
