https://notcve.org/view.php?id=CVE-2012-0876
03 Jul 2012 — 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. El analizador XML (xmlparse.c) en expat antes de v2.1.0 calcula los valores de hash sin restringir la capacidad de desencadenar colisiones hash de forma predecible, lo que permite causar una denegación de servicio (por con... • http://bugs.python.org/issue13703#msg151870 • CWE-400: Uncontrolled Resource Consumption CWE-407: Inefficient Algorithmic Complexity •
