SOL16364: GNU C Library (glibc) vulnerability CVE-2012-3406
Security Advisory
Original Publication Date: 04/03/2015
Description
The vfprintf function in stdio-common/vfprintf.c in GNU C Library (aka glibc)
2.5, 2.12, and probably other versions does not "properly restrict the use of"
the alloca function when allocating the SPECS array, which allows
context-dependent attackers to bypass the FORTIFY_SOURCE format-string
protection mechanism and cause a denial of service (crash) or possibly execute
arbitrary code via a crafted format string using positional parameters and a
large number of format specifiers, a different vulnerability than
CVE-2012-3404 and CVE-2012-3405. (CVE-2012-3406)
Impact
An attacker with local access and knowledge of how to make the glibc function
trigger an exploit may be able to cause a denial-of-service (DoS) or run
arbitrary code.
Status
F5 Product Development has assigned ID 391780 (BIG-IP) to this vulnerability,

Note: As of February 17, 2015, AskF5 Security Advisory articles include the
Severity value. Security Advisory articles published before this date do not
list a Severity value.
Recommended Action
If the previous table lists a version in the Versions known to be not
vulnerable column, you can eliminate this vulnerability by upgrading to the
listed version. If the listed version is older than the version you are
currently running, or if the table does not list any version in the column,
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 permit access to F5 products only
over a secure network, and limit login access to trusted users. For additional
information, refer to SOL13092: Overview of securing access to the BIG-IP
system.
