FKIE_CVE-2012-0876
Vulnerability from fkie_nvd - Published: 2012-07-03 19:55 - Updated: 2025-04-11 00:51
Severity ?
Summary
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.
