K21632201: Linux kernel vulnerability CVE-2011-5321

Security Advisory

Original Publication Date: Apr 08, 2016

Updated Date: Oct 25, 2017

Security Advisory Description

The tty_open function in drivers/tty/tty_io.c in the Linux kernel before 3.1.1
mishandles a driver-lookup failure, which allows local users to cause a denial
of service (NULL pointer dereference and system crash) or possibly have
unspecified other impact via crafted access to a device file under the /dev/pts
directory. (CVE-2011-5321)

Impact

A local, unprivileged user may exploit this vulnerability and create a
situation where the system stops responding.

In the default configuration, only an administrator user has advanced shell
access. If a non-administrator user is given advanced shell access in a
non-default configuration, then the possibility of privilege escalation
increases the exposure of this vulnerability.

Security Advisory Status

F5 Product Development has assigned ID 533413 (BIG-IP), ID 542392 (BIG-IQ), ID
542393 (Enterprise Manager), and INSTALLER-2305 (Traffix SDC) to this
vulnerability, and has evaluated the currently supported releases for potential
vulnerability. Additionally, BIG-IP iHealth may list Heuristic H21632201 on the
Diagnostics > Identified > Low screen.

Security Advisory Recommended Actions

If you are running a version listed in the Versions known to be vulnerable
column, you can eliminate this vulnerability by upgrading to a version listed
in the Versions known to be not vulnerable column. If the table lists only an
older version than what you are currently running, or does not list a
non-vulnerable version, then no upgrade candidate currently exists.

Mitigation

To mitigate this vulnerability for affected BIG-IP/Enterprise Manager products,
you should limit shell access to only trusted users. For more information about
securing access to BIG-IP/Enterprise Manager systems, refer to K13092: Overview
of securing access to the BIG-IP system.

Security Advisory Recommended Actions

If you are running a version listed in the Versions known to be vulnerable
column, you can eliminate this vulnerability by upgrading to a version listed
in the Versions known to be not vulnerable column. If the table lists only an
older version than what you are currently running, or does not list a
non-vulnerable version, then no upgrade candidate currently exists.

To determine the necessary upgrade path for your BIG-IQ system, you should
understand the BIG-IQ product offering name changes. For more information,
refer to K21232150: Considerations for upgrading BIG-IQ or F5 iWorkflow systems
.

Final - K95345942: Linux kernel vulnerability CVE-2015-3339

Security Advisory

Original Publication Date: Jan 30, 2016

Updated Date: Oct 26, 2017

The security issue described in this article has been resolved or does not
affect any F5 products. There will be no further updates, unless new
information is discovered.

Security Advisory Description

Race condition in the prepare_binprm function in fs/exec.c in the Linux kernel
before 3.19.6 allows local users to gain privileges by executing a setuid
program at a time instant when a chown to root is in progress, and the
ownership is changed but the setuid bit is not yet stripped. (CVE-2015-3339)

Impact

A local user with advanced shell (bash) access on a BIG-IP system, or with
local administrator access on a Traffix system, may be able to use this flaw to
gain elevated privileges. In supported configurations on the BIG-IP system,
advanced shell access is limited to system administrators. BIG-IP appliance
mode does not expose this issue, as users are not allowed advanced shell access
in this mode. On Traffix systems, only administrators have local access.

Security Advisory Status

F5 Product Development has assigned ID 540018 (BIG-IP), ID 569537 (BIG-IQ), and
ID 569538 (Enterprise Manager) to this vulnerability, and has evaluated the
currently supported releases for potential vulnerability. Additionally, BIG-IP
iHealth may list Heuristic H95345942 on the Diagnostics > Identified > Medium
screen.

Security Advisory Recommended Actions

If you are running a version listed in the Versions known to be vulnerable
column, you can eliminate this vulnerability by upgrading to a version listed
in the Versions known to be not vulnerable column. If the table lists only an
older version than what you are currently running, or does not list a
non-vulnerable version, then no upgrade candidate currently exists.

To determine the necessary upgrade path for your BIG-IQ system, you should
understand the BIG-IQ product offering name changes. For more information,
refer to K21232150: Considerations for upgrading BIG-IQ or F5 iWorkflow systems
.

Mitigation

BIG-IP

To mitigate this vulnerability, allow only trusted admin users to have access
to Advanced Shell (bash). Appliance mode does not expose this issue, as users
are not allowed Advanced Shell (bash) access in this mode.

Traffix SDC

To mitigate this vulnerability, you can upgrade with the Traffix package for
October 2015 (4.4 CF 9) or later versions, which includes the kernel fix. For
more information, refer to the F5 Traffix representative for your region.

K17246: Linux kernel vulnerability CVE-2015-3636

Security Advisory

Original Publication Date: Sep 09, 2015
Updated Date: Oct 26, 2017

Security Advisory Description

The ping_unhash function in net/ipv4/ping.c in the Linux kernel before 4.0.3
does not initialize a certain list data structure during an unhash operation,
which allows local users to gain privileges or cause a denial of service
(use-after-free and system crash) by leveraging the ability to make a
SOCK_DGRAM socket system call for the IPPROTO_ICMP or IPPROTO_ICMPV6 protocol,
and then making a connect system call after a disconnect. (CVE-2015-3636)

Impact

A locally authenticated user, with a role that allows advanced shell access,
may be able to escalate privileges or cause a denial-of-service (DoS) attack.

Security Advisory Status

F5 Product Development has assigned ID 533413 (BIG-IP), ID 542392 (BIG-IQ), ID
542393 (Enterprise Manager), and ID 461496 (ARX) to this vulnerability, and has
evaluated the currently supported releases for potential vulnerability.
Additionally, BIG-IP iHealth may list Heuristic H542906 on the Diagnostics >
Identified > Medium screen.

To determine if your release is known to be vulnerable, the components or
features that are affected by the vulnerability, and for information about
releases or hotfixes that address the vulnerability, refer to the following

Security Advisory Recommended Actions

If you are running a version listed in the Versions known to be vulnerable
column, you can eliminate this vulnerability by upgrading to a version listed
in the Versions known to be not vulnerable column. If the table lists only an
older version than what you are currently running, or does not list a
non-vulnerable version, then no upgrade candidate currently exists.

To determine the necessary upgrade path for your BIG-IQ system, you should
understand the BIG-IQ product offering name changes. For more information,
refer to K21232150: Considerations for upgrading BIG-IQ or F5 iWorkflow systems
.

Mitigation

To mitigate this vulnerability, you should only permit management access to F5
products over a secure network, and restrict command line access for the
affected systems to trusted users. For more information, refer to K13309:
Restricting access to the Configuration utility by source IP address (11.x -
13.x) and K13092: Overview of securing access to the BIG-IP system.

K90230486: Linux kernel vulnerability CVE-2015-7613

Security Advisory

Original Publication Date: Dec 04, 2015
Updated Date: Oct 25, 2017

Security Advisory Description

Race condition in the IPC object implementation in the Linux kernel through
4.2.3 allows local users to gain privileges by triggering an ipc_addid call
that leads to uid and gid comparisons against uninitialized data, related to
msg.c, shm.c, and util.c. (CVE-2015-7613)

Impact

Exploitation of this issue requires shell access, and a non-standard and
unsupported configuration (such as modifications to Linux configuration files)
may expose this issue further. F5 does not recommend manually editing Linux
configuration files. There is no remote access vector or data plane exposure.

Security Advisory Status

F5 Product Development has assigned IDs 556740 and 563154 (BIG-IP), IDs 558161
and 565223 (Enterprise Manager), IDs 558159 and 565221 (BIG-IQ), and
INSTALLER-2102 (Traffix SDC) to this vulnerability, and has evaluated the
currently supported releases for potential vulnerability.

To determine if your release is known to be vulnerable, the components or
features that are affected by the vulnerability, and for information about
releases or hotfixes that address the vulnerability, refer to the following

Security Advisory Description

The (1) pipe_read and (2) pipe_write implementations in fs/pipe.c in a certain
Linux kernel backport in the linux package before 3.2.73-2+deb7u3 on Debian
wheezy and the kernel package before 3.10.0-229.26.2 on Red Hat Enterprise
Linux (RHEL) 7.1 do not properly consider the side effects of failed
__copy_to_user_inatomic and __copy_from_user_inatomic calls, which allows local
users to cause a denial of service (system crash) or possibly gain privileges
via a crafted application, aka an "I/O vector array overrun." NOTE: this
vulnerability exists because of an incorrect fix for CVE-2015-1805. (
CVE-2016-0774)

Impact

A local unprivileged user may be able to leak kernel memory to user space or
cause a denial of service (DoS).

K31603170: Linux kernel vulnerability CVE-2016-7097

Security Advisory

Original Publication Date: Jun 23, 2017
Updated Date: Oct 24, 2017

Security Advisory Description

The filesystem implementation in the Linux kernel through 4.8.2 preserves the
setgid bit during a setxattr call, which allows local users to gain group
privileges by leveraging the existence of a setgid program with restrictions on
execute permissions. (CVE-2016-7097)

Impact

A local user may be allowed to gain group privileges by way of certain setgid 
applications.

Security Advisory Status

F5 Product Development has assigned ID 652516 (BIG-IP), ID 669855 (BIG-IQ), ID
670353 (F5 iWorkflow), and ID 669854 (Enterprise Manager) to this
vulnerability. Additionally, BIG-IP iHealth may list Heuristic H31603170 on the

Security Advisory Recommended Actions

If you are running a version listed in the Versions known to be vulnerable
column, you can eliminate this vulnerability by upgrading to a version listed
in the Versions known to be not vulnerable column. If the table lists only an
older version than what you are currently running, or does not list a
non-vulnerable version, then no upgrade candidate currently exists.

To determine the necessary upgrade path for your BIG-IQ system, you should
understand the BIG-IQ product offering name changes. For more information,
refer to K21232150: Considerations for upgrading BIG-IQ or F5 iWorkflow systems

K31026324: Linux kernel vulnerabilities CVE-2015-2925, CVE-2015-5307, and
CVE-2015-8104

Security Advisory

Original Publication Date: Jan 14, 2016
Updated Date: Oct 26, 2017

Security Advisory Description

  o CVE-2015-2925

    The prepend_path function in fs/dcache.c in the Linux kernel before 4.2.4
    does not properly handle rename actions inside a bind mount, which allows
    local users to bypass an intended container protection mechanism by
    renaming a directory, related to a "double-chroot attack."

  o CVE-2015-5307

    The KVM subsystem in the Linux kernel through 4.2.6, and Xen 4.3.x through
    4.6.x, allows guest OS users to cause a denial of service (host OS panic or
    hang) by triggering many #AC (aka Alignment Check) exceptions, related to
    svm.c and vmx.c.

  o CVE-2015-8104

    The KVM subsystem in the Linux kernel through 4.2.6, and Xen 4.3.x through
    4.6.x, allows guest OS users to cause a denial of service (host OS panic or
    hang) by triggering many #DB (aka Debug) exceptions, related to svm.c.

Impact

A local user may be able to bypass a container protection mechanism by renaming
a directory, or cause a denial of service (DoS) to the system by triggering
certain exceptions.
