The msrle_decode_pal4 function in msrledec.c in Libav before 10.7 and 11.x before 11.4 and FFmpeg before 2.0.7, 2.2.x before 2.2.15, 2.4.x before 2.4.8, 2.5.x before 2.5.6, and 2.6.x before 2.6.2 allows remote attackers to have unspecified impact via a crafted image, related to a pixel pointer, which triggers an out-of-bounds array access.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
