* This vulnerability is rated as Low because exploiting it requires physical
access (to plug in a specially prepared USB disk) or root access (to mount a
specially prepared file system) to the system.
Vulnerability 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.
F5 responds to vulnerabilities in accordance with the Severity values
published in the previous table. The Severity values and other security
vulnerability parameters are defined in SOL4602: Overview of the F5 security
vulnerability response policy.
To mitigate this vulnerability, you should only permit authorized physical
access to F5 products. Additionally, you should only permit management access
to F5 products over a secure network and limit shell access to trusted users.
For more information about securing access to BIG-IP/Enterprise Manager
systems, refer to SOL13309: Restricting access to the Configuration utility by
source IP address (11.x - 12.x) and SOL13092: Overview of securing access to
the BIG-IP system.

sol95345942: Linux kernel vulnerability CVE-2015-3339
Security Advisory
Original Publication Date: 01/29/2016
Vulnerability 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 Issue Status
F5 Product Development has assigned ID 570272 to this vulnerability, and has
evaluated the currently supported releases for potential vulnerability.

BIG-IP
To mitigate this vulnerability, allow only trusted admin users to have access
to advanced shell. Appliance mode does not expose this issue, as users are not
allowed advanced shell 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.

Security Advisory
Original Publication Date: 01/28/2016
Vulnerability Description
The sctp_init function in net/sctp/protocol.c in the Linux kernel before 4.2.3
has an incorrect sequence of protocol-initialization steps, which allows local

Vulnerability 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.
