CVE-2013-0339

libxml2 through 2.9.1 does not properly handle external entities expansion
unless an application developer uses the xmlSAX2ResolveEntity or
xmlSetExternalEntityLoader function, which allows remote attackers to cause
a denial of service (resource consumption), send HTTP requests to intranet
servers, or read arbitrary files via a crafted XML document, aka an XML
External Entity (XXE) issue. NOTE: it could be argued that because libxml2
already provides the ability to disable external entity expansion, the
responsibility for resolving this issue lies with application developers;
according to this argument, this entry should be REJECTed and each affected
application would need its own CVE.
