CVE-2012-0876
No CVSS score yet. EPSS 5.7% chance of exploitation in the next 30 days.
The XML parser (xmlparse.c) in expat before 2.1.0 computes hash values without restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via an XML file with many identifiers with the same value.
