sol16057: GHOST: glibc gethostbyname buffer overflow vulnerability 
CVE-2015-0235

Security Advisory

Original Publication Date: 01/27/2015

Updated Date: 02/06/2015

Description

A heap-based buffer overflow was found in glibc's __nss_hostname_digits_dots()
function, which is used by the gethostbyname() and gethostbyname2() glibc 
function calls. A remote attacker may be able to use this flaw to execute 
arbitrary code. (CVE-2015-0235)

Impact

A remote attacker may be able to execute arbitrary code.

Status

F5 Product Development has assigned ID 503237 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 
table:

*F5 has determined that these products contain vulnerable versions of glibc, 
and the vulnerable function is used in the product; however, at this time F5 
does not have evidence of any remote exploit vectors for this vulnerability.

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 is working to provide a patch 
for this issue, and will update this article as soon as a patch becomes 
available.

F5 is responding to this vulnerability as determined by the parameters defined
in SOL4602: Overview of the F5 security vulnerability response policy.

To mitigate this vulnerability, you should only permit access to F5 products 
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.
