Description

The ff_h264_decode_seq_parameter_set function in h264_ps.c in libavcodec in FFmpeg before 1.1.3 does not validate the relationship between luma depth and chroma depth, which allows remote attackers to cause a denial of service (out-of-bounds array access and application crash) or possibly have unspecified other impact via crafted H.264 data.

Affected products

FFmpeg: through 1.1.2; 0.3, 0.3.1, 0.3.2, 0.3.3, 0.3.4, 0.4.0 (+51)
