CVE-2014-9602 (GCVE-0-2014-9602)

Vulnerability from cvelistv5 – Published: 2015-01-16 20:00 – Updated: 2024-08-06 13:47

Summary

libavcodec/xface.h in FFmpeg before 2.5.2 establishes certain digits and words array dimensions that do not satisfy a required mathematical relationship, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted X-Face image data.

Severity ?
