CWE-125

Description

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.

Affected configurations

• xiph theora • redhat enterprise linux 6.0 • redhat enterprise linux 7.0 • redhat enterprise linux 8.0 • redhat enterprise linux 9.0 • redhat enterprise linux 10.0
