CVE-2023-5595Public exploit

Application crash via malformed ISO media boxes

Published Oct 16, 2023 · Updated Sep 16, 2024

Null-pointer dereference in GPAC before 2.3.0-DEV allows context-dependent attackers to crash MP4Box through a crafted media file. MP4Box's ISO media paths dereference missing tx3g font-table and LASeR configuration pointers and duplicate a null chapter-text pointer. The target must open or process the crafted file, after which the affected MP4Box process terminates without reported confidentiality or integrity impact.
