An issue was discovered in Libav 12.3. A read access violation in the in_table_init16 function in libavcodec/aacsbr.c allows remote attackers to cause a denial of service (application crash), as demonstrated by avconv.
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.
