Security update for libxml2
SUSE Security Update: Security update for libxml2
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.
