"From Red Hat Security Advisory 2017:1842 :

An update for kernel is now available for Red Hat Enterprise Linux 7.

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 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, Important)

* A flaw was found that can be triggered in keyring_search_iterator in
keyring.c if type->match is NULL. A local user could use this flaw to
crash the system or, potentially, escalate their privileges.
(CVE-2017-2647, Important)

* It was found that the NFSv4 server in the Linux kernel did not
properly validate layout type when processing NFSv4 pNFS LAYOUTGET and
GETDEVICEINFO operands. A remote attacker could use this flaw to
soft-lockup the system and thus cause denial of service.
(CVE-2017-8797, Important)

This update also fixes multiple Moderate and Low impact security
issues :

* CVE-2015-8839, CVE-2015-8970, CVE-2016-9576, CVE-2016-7042,
CVE-2016-7097, CVE-2016-8645, CVE-2016-9576, CVE-2016-9588,
CVE-2016-9806, CVE-2016-10088, CVE-2016-10147, CVE-2017-2596,
CVE-2017-2671, CVE-2017-5970, CVE-2017-6001, CVE-2017-6951,
CVE-2017-7187, CVE-2017-7616, CVE-2017-7889, CVE-2017-8890,
CVE-2017-9074, CVE-2017-8890, CVE-2017-9075, CVE-2017-8890,
CVE-2017-9076, CVE-2017-8890, CVE-2017-9077, CVE-2017-9242,
CVE-2014-7970, CVE-2014-7975, CVE-2016-6213, CVE-2016-9604,
CVE-2016-9685

Documentation for these issues is available from the Release Notes
document linked from the References section.

"According to the version of the vzkernel package and the
readykernel-patch installed, the Virtuozzo installation on the remote
host is affected by the following vulnerabilities :

  - The NFSv4 server in the Linux kernel compiled with
    CONFIG_NFSD_PNFS enabled does not properly validate
    layout type when processing NFSv4 pNFS LAYOUTGET and
    GETDEVICEINFO operands. The attack payload fits to
    single one-way UDP packet. The provided input value is
    used for array dereferencing. This may lead to a remote
    DoS of [knfsd] and so to a soft-lockup of a whole
    system.

  - A flaw was found in the way Linux kernel allocates heap
    memory to build the scattergather list from a fragment
    list(skb_shinfo(skb)->frag_list) in the socket
    buffer(skb_buff). The heap overflow occurred if
    'MAX_SKB_FRAGS + 1' parameter and 'NETIF_F_FRAGLIST'
    feature are both used together. A remote user or
    process could use this flaw to potentially escalate
    their privilege on a system.

  - A vulnerability was found in the implementation of
    setsockopt() operations in the Linux kernel. A
    privileged user inside a container could cause a DoS
    attack on the host (kernel deadlock in ip_ra_control()
    function) using a specially crafted sequence of system
    calls.

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.");

"An update for kernel is now available for Red Hat Enterprise Linux 7.

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 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, Important)

* A flaw was found that can be triggered in keyring_search_iterator in
keyring.c if type->match is NULL. A local user could use this flaw to
crash the system or, potentially, escalate their privileges.
(CVE-2017-2647, Important)

* It was found that the NFSv4 server in the Linux kernel did not
properly validate layout type when processing NFSv4 pNFS LAYOUTGET and
GETDEVICEINFO operands. A remote attacker could use this flaw to
soft-lockup the system and thus cause denial of service.
(CVE-2017-8797, Important)

This update also fixes multiple Moderate and Low impact security
issues :

* CVE-2015-8839, CVE-2015-8970, CVE-2016-9576, CVE-2016-7042,
CVE-2016-7097, CVE-2016-8645, CVE-2016-9576, CVE-2016-9588,
CVE-2016-9806, CVE-2016-10088, CVE-2016-10147, CVE-2017-2596,
CVE-2017-2671, CVE-2017-5970, CVE-2017-6001, CVE-2017-6951,
CVE-2017-7187, CVE-2017-7616, CVE-2017-7889, CVE-2017-8890,
CVE-2017-9074, CVE-2017-8890, CVE-2017-9075, CVE-2017-8890,
CVE-2017-9076, CVE-2017-8890, CVE-2017-9077, CVE-2017-9242,
CVE-2014-7970, CVE-2014-7975, CVE-2016-6213, CVE-2016-9604,
CVE-2016-9685

Documentation for these issues is available from the Release Notes
document linked from the References section.

Red Hat would like to thank Igor Redko (Virtuozzo) and Andrey Ryabinin
(Virtuozzo) for reporting CVE-2017-2647; Igor Redko (Virtuozzo) and
Vasily Averin (Virtuozzo) for reporting CVE-2015-8970; Marco Grassi
for reporting CVE-2016-8645; and Dmitry Vyukov (Google Inc.) for
reporting CVE-2017-2596. The CVE-2016-7042 issue was discovered by
Ondrej Kozina (Red Hat); the CVE-2016-7097 issue was discovered by
Andreas Gruenbacher (Red Hat) and Jan Kara (SUSE); the CVE-2016-6213
and CVE-2016-9685 issues were discovered by Qian Cai (Red Hat); and

"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) :

* A race condition was found in the Linux kernel, present since
v3.14-rc1 through v4.12. The race happens between threads of
inotify_handle_event() and vfs_rename() while running the rename
operation against the same file. As a result of the race the next slab
data or the slab's free list pointer can be corrupted with
attacker-controlled data, which may lead to the privilege escalation.
(CVE-2017-7533, Important)

* It was found that the NFSv4 server in the Linux kernel did not
properly validate layout type when processing NFSv4 pNFS LAYOUTGET and
GETDEVICEINFO operands. A remote attacker could use this flaw to
soft-lockup the system and thus cause denial of service.
(CVE-2017-8797, Important)

This update also fixes multiple Moderate and Low impact security
issues :

Documentation for these issues are available from the Technical Notes
document linked to in the References section.

Red Hat would like to thank Leilei Lin (Alibaba Group), Fan Wu (The
University of Hong Kong), and Shixiong Zhao (The University of Hong
Kong) for reporting CVE-2017-7533 and Marco Grassi for reporting
CVE-2016-8645. The CVE-2016-7042 issue was discovered by Ondrej Kozina
(Red Hat); the CVE-2016-7097 issue was discovered by Andreas
Gruenbacher (Red Hat) and Jan Kara (SUSE); the CVE-2016-9604 issue was
discovered by David Howells (Red Hat); and the CVE-2016-9685 issue was
discovered by Qian Cai (Red Hat)."

"According to the version of the vzkernel package and the
readykernel-patch installed, the Virtuozzo installation on the remote
host is affected by the following vulnerabilities :

  - The NFSv4 server in the Linux kernel compiled with
    CONFIG_NFSD_PNFS enabled does not properly validate
    layout type when processing NFSv4 pNFS LAYOUTGET and
    GETDEVICEINFO operands. The attack payload fits to
    single one-way UDP packet. The provided input value is
    used for array dereferencing. This may lead to a remote
    DoS of [knfsd] and so to a soft-lockup of a whole
    system.

  - A vulnerability was found in the implementation of
    setsockopt() operations in the Linux kernel. A
    privileged user inside a container could cause a DoS
    attack on the host (kernel deadlock in ip_ra_control()
    function) using a specially crafted sequence of system
    calls.

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.");
