CentOS Errata and Security Advisory CESA-2012:1512
The libxml2 library is a development toolbox providing the implementation
of various XML standards.
A heap-based buffer underflow flaw was found in the way libxml2 decoded
certain entities. 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-2012-5134)
All users of libxml2 are advised to upgrade to these updated packages,
which contain a backported patch to correct this issue. The desktop must be
restarted (log out, then log back in) for this update to take effect.
