K51079478: glibc vulnerability CVE-2015-8778

Security Advisory


Original Publication Date: Apr 08, 2016
Updated Date: Dec 14, 2018


Security Advisory Description

Integer overflow in the GNU C Library (aka glibc or libc6) before 2.23 allows
context-dependent attackers to cause a denial of service (application crash) or
possibly execute arbitrary code via the size argument to the __hcreate_r
function, which triggers out-of-bounds heap-memory access. (CVE-2015-8778)

Impact

There is a theoretical risk of an exploit by a user with local shell access. F5
has been unable to reproduce the vulnerability using proof of concept code.

Security Advisory Status

F5 Product Development has assigned ID 578983 (BIG-IP), CPF-19112 (Traffix
SDC), and ID 476571 (ARX) to this vulnerability, and has evaluated the
currently supported releases for potential vulnerability. Additionally, BIG-IP
iHealth may list Heuristic H51079478 on the Diagnostics > Identified > Low
page.

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

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.
