CVE-2013-0338

Publication date 26 February 2013

Last updated 24 July 2024

Ubuntu priority

libxml2 2.9.0 and earlier allows context-dependent attackers to cause a denial of service (CPU and memory consumption) via an XML file containing an entity declaration with long replacement text and many references to this entity, aka "internal entity expansion" with linear complexity.
