Description

This security bulletin contains information about 1 security vulnerability.


1) Resource management error (CVE-ID: CVE-2012-0876)

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

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.
