Overview
An issue was discovered in GPAC from v0.5.2 to v0.8.0, as demonstrated by MP4Box. It contains a heap-based buffer overflow in gf_m2ts_section_complete in media_tools/mpegts.c that can cause a denial of service (DOS) via a crafted MP4 file (NVD).
Technical details
The vulnerability exists in the gf_m2ts_section_complete function within the media_tools/mpegts.c file. The issue occurs when processing MPEG-2 TS sections, where improper bounds checking leads to a heap buffer overflow condition. The vulnerability has been assigned a CVSS v3.1 Base Score of 5.5 MEDIUM (Vector: CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H) (NVD).
Impact
When exploited, this vulnerability can lead to a denial of service condition through a heap-based buffer overflow. The attack requires user interaction to process a specially crafted MP4 file (NVD).
Mitigation and workarounds
A fix has been implemented and committed to the GPAC repository. The patch addresses the buffer overflow by adding proper bounds checking in the affected code section (GPAC Commit).
