Heap-based buffer overflow in the ff_audio_resample function in resample.c in libav before 11.4 allows remote attackers to cause a denial of service (crash) via vectors related to buffer resizing.
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.
