Synopsis: Moderate: libxml2 security update
Issue Date: 2012-09-18
CVE Numbers: CVE-2011-3102
 CVE-2012-2807

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

Multiple integer overflow flaws, leading to heap-based buffer overflows,
were found in the way libxml2 handled documents that enable entity
expansion. A remote attacker could provide a large, 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-2012-2807)

A one byte buffer overflow was found in the way libxml2 evaluated certain
parts of XML Pointer Language (XPointer) expressions. 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-2011-3102)

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.
