Category:Red Hat Local Security Checks
Title:RedHat Update for libxml2 RHSA-2012:0018-01
Summary:The remote host is missing an update for the 'libxml2'; package(s) announced via the referenced advisory.
Description:Summary:
The remote host is missing an update for the 'libxml2'
package(s) announced via the referenced advisory.

Vulnerability Insight:
The libxml2 library is a development toolbox providing the implementation
of various XML standards.

A heap-based buffer overflow flaw was found in the way libxml2 decoded
entity references with long names. A remote attacker could provide a
specially-crafted XML file that, when opened in an application linked
against libxml2, would cause the application to crash or, potentially,
execute arbitrary code with the privileges of the user running the
application. (CVE-2011-3919)

An out-of-bounds memory read flaw was found in libxml2. A remote attacker
could provide a specially-crafted XML file that, when opened in an
application linked against libxml2, would cause the application to crash.
(CVE-2011-3905)

All users of libxml2 are advised to upgrade to these updated packages,
which contain backported patches to correct these issues. The desktop must
be restarted (log out, then log back in) for this update to take effect.

Affected Software/OS:
libxml2 on Red Hat Enterprise Linux Desktop (v. 6),
Red Hat Enterprise Linux Server (v. 6),
Red Hat Enterprise Linux Workstation (v. 6)

Solution:
Please Install the Updated Packages.
