CVE-2024-57509Public exploit

Local code execution via oversized memory-stream copy

Published Jan 29, 2025 · Updated Jan 31, 2025

Heap buffer overflow in Bento4 mp42avc at 3bdc891602d19789b8e8626e4a3e613a937b4d35 allows local users to execute arbitrary code. When parsing a crafted MP4, AP4_MemoryByteStream::WritePartial passes a 4,294,967,294-byte length to memcpy for a 1,052-byte heap allocation, causing an out-of-bounds write. A local user must invoke mp42avc on the file; the published demonstration aborts under AddressSanitizer, while the CVE record states that the write allows code execution in the process.
