In Libav through 12.2, there is an invalid memcpy in the av_packet_ref function of libavcodec/avpacket.c. Remote attackers could leverage this vulnerability to cause a denial of service (segmentation fault) via a crafted avi file.
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.
