Description:


   libxml2 has been updated to fix two security bugs.

   * CVE-2013-0338: Internal entity expansion within XML
   was not bounded, leading to simple small XML files being
   able to cause "out of memory" denial of service conditions.
   * CVE-2012-5134: Heap-based buffer underflow in the
   xmlParseAttValueComplex function in parser.c in libxml2
   allowed remote attackers to cause a denial of service or
   possibly execute arbitrary code via crafted entities in an
   XML document.
