| 标题 | GPAC master f1219cde (2026-07-25) Buffer Overflow |
|---|
| 描述 | A heap-buffer-overflow vulnerability exists in GPAC master (commit f1219cde, 2026-07-25). The issue occurs in the mpgviddmx_process function in filters/reframe_mpgvid.c at line 1190 during MPEG video import via MP4Box -add. When processing a crafted MPEG Part-2 video bitstream, the MPEG video reframer reads past the input buffer (READ of size 1, 0 bytes to the right of a 2-byte region). This is reachable from gf_media_import and may be an incomplete fix for issue #2795. The vulnerability can be triggered with: MP4Box -add poc -new out.mp4. PoC and ASan crash log are available in the GitHub issue report. |
