CVE-2024-31003Public exploitNetwork attack vector

Arbitrary code execution via oversized memory-stream copy

Published Apr 2, 2024 · Updated Mar 25, 2025

Heap buffer overflow in Bento4 1.6.0-641 allows remote attackers to execute arbitrary code through a crafted media file processed by mp42aac. AP4_MemoryByteStream::WritePartial passes a crafted 32-bit length to memcpy, causing a 4,294,967,280-byte write beyond a 1,056-byte heap buffer. Exploitation requires the target to process the malicious file with mp42aac; the published proof demonstrates an AddressSanitizer abort, while the CVE record attributes arbitrary code execution.
