Description : A flaw was found in the libxml2 library. This uncontrolled resource consumption vulnerability occurs when processing XML catalogs that contain repeated elements pointing to the same downstream catalog.

This leads to excessive CPU consumption and degrades application availability, resulting in a denial-of-service condition.
