NVD Description

Note: Versions mentioned in the description apply only to the upstream libtheora package and not the libtheora package as distributed by Centos. See How to fix? for Centos:6 relevant fixed versions and status.

A flaw was found in libtheora. This heap-based out-of-bounds read vulnerability exists within the AVI (Audio Video Interleave) parser, specifically in the avi_parse_input_file() function. A local attacker could exploit this by tricking a user into opening a specially crafted AVI file containing a truncated header sub-chunk. This could lead to a denial-of-service (application crash) or potentially leak sensitive information from the heap.
