CVE-2023-3291Public exploit

Application crash via undersized ID3 buffer

Published Jun 16, 2023 · Updated Dec 17, 2024

Heap-based buffer overflow in GPAC before 2.2.2 allows local users to crash MP4Box by inspecting a crafted MP3 file. The id3dmx_flush function fails to grow its heap buffer when existing capacity exceeds the frame size by only one or two bytes, then appends data beyond the allocation. A vulnerable local MP4Box process must inspect the crafted file; the demonstrated consequence is an application crash.
