Severity ?

CWE

Summary

The decode_uncompressed function in libavcodec/faxcompr.c in FFmpeg before 2.8.2 does not validate uncompressed runs, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted CCITT FAX data.
