CVSS: 5.0EPSS: 0%CPEs: 22EXPL: 0CVE-2012-0876 – expat: hash table collisions CPU usage DoS
https://notcve.org/view.php?id=CVE-2012-0876
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 consumo de CPU) a atacantes dependientes de contexto a través de un archivo XML con muchos identificadores con el mismo valor. A denial of service flaw was found in the implementation of hash arrays in Expat. An attacker could use this flaw to make an application using Expat consume an excessive amount of CPU time by providing a specially crafted XML file that triggers multiple hash function collisions. To mitigate this issue, randomization has been added to the hash function to reduce the chance of an attacker successfully causing intentional collisions. • http://bugs.python.org/issue13703#msg151870 http://lists.apple.com/archives/security-announce/2013/Oct/msg00004.html http://lists.apple.com/archives/security-announce/2015/Dec/msg00005.html http://mail.libexpat.org/pipermail/expat-discuss/2012-March/002768.html http://rhn.redhat.com/errata/RHSA-2012-0731.html http://rhn.redhat.com/errata/RHSA-2016-0062.html http://rhn.redhat.com/errata/RHSA-2016-2957.html http://secunia.com/advisories/49504 http://secunia.com/advisories/51024 • CWE-400: Uncontrolled Resource Consumption CWE-407: Inefficient Algorithmic Complexity •
