CVE-2014-9603 (GCVE-0-2014-9603)

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

Summary

The vmd_decode function in libavcodec/vmdvideo.c in FFmpeg before 2.5.2 does not validate the relationship between a certain length value and the frame width, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted Sierra VMD video data.

Severity ?

No CVSS data available.
