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.

Notes

Author Note
ebarretto tla uses system expat as of 1.3.5+dfsg-15
rodrigo-zaiden it is also an incomplete fix for CVE-2012-6702, that followed CVE-2012-0876. libxmltok is not affected by any of these CVEs as it doesn’t have the hash functions.
