### Description

The XML parser in Expat does not use sufficient entropy for hash initialization, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted identifiers in an XML document.  NOTE: this vulnerability exists because of an incomplete fix for CVE-2012-0876.
