CVE-2025-70116: n/a
A NULL pointer dereference in GPAC MP4Box: when parsing certain truncated MP4 files, an unknown/invalid stsd entry can result in missing descriptor fields (e.g., codec/mime/profile strings). gf_media_map_esd then calls strlen() on a NULL pointer, triggering a crash (ASan SEGV).
AI Analysis
Technical Summary
This vulnerability involves a NULL pointer dereference in GPAC MP4Box triggered when parsing malformed or truncated MP4 files containing unknown or invalid stsd entries. The missing descriptor fields such as codec, mime, or profile strings cause the function gf_media_map_esd to call strlen() on a NULL pointer, leading to a segmentation fault and application crash. The CVSS score is 4.3 (medium severity) with network attack vector, low attack complexity, no privileges required, user interaction needed, and impacts availability only.
Potential Impact
The primary impact is a denial of service due to application crashes when processing crafted MP4 files. There is no impact on confidentiality or integrity. No known active exploitation has been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, avoid processing untrusted or malformed MP4 files with GPAC MP4Box to reduce risk of crashes.
