K64119434:GNU C Library vulnerability CVE-2009-5155

Security Advisory

Original Publication Date: 26 Mar, 2019

Security Advisory Description

In the GNU C Library (aka glibc or libc6) before 2.28, parse_reg_exp in posix/
regcomp.c misparses alternatives, which allows attackers to cause a denial of
service (assertion failure and application exit) or trigger an incorrect result
by attempting a regular-expression match. (CVE-2009-5155)

Impact

An attacker can exploit this vulnerability to cause a denial of service on the
affected system.

Security Advisory Status

F5 Product Development has assigned ID 760895 (BIG-IP), ID 760895-1 (BIG-IQ),
and ID CPF-25071 and CPF-25072 (Traffix SDC) to this vulnerability.

To determine if your product and version have been evaluated for this
vulnerability, refer to the Applies to (see versions) box. 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. For more information
about security advisory versioning, refer to K51812227: Understanding Security

possible that the document may be removed without our knowledge.

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 Fixes introduced in 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, you should permit connectivity access to the
affected F5 products only over a secure network and restrict access to the
affected systems to only trusted users. For more information, refer to the
following articles:
