Local code execution via oversized memory copy
Published Jan 29, 2025 · Updated Feb 3, 2025
Heap buffer overflow in Bento4 mp42avc commit 3bdc891 allows local users to execute arbitrary code through a crafted MP4 file. AP4_MemoryByteStream::WritePartial passes an underflowed unsigned length of 4,294,967,294 to memcpy, which writes beyond a 1,052-byte heap allocation. Exploitation requires local execution of mp42avc against the file and runs code with the process's privileges.
