In Libav 12.3, there is an invalid memory access in vc1_decode_frame in libavcodec/vc1dec.c that allows attackers to cause a denial-of-service via a crafted aac file. NOTE: This may be a duplicate of CVE-2017-17127
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.
