| タイトル | GPAC 26.03-DEV Buffer Overflow |
|---|
| 説明 | A heap buffer overflow vulnerability was found in GPAC version 26.03-DEV. The issue affects the function svgin_process() in the file src/filters/load_svg.c. When processing DIMS data, the inner unit size read from the bitstream (line 201) overwrites the outer packet size used for buffer allocation (line 192). This results in an out-of-bounds read at line 210 and an out-of-bounds write at line 212 via a crafted MP4 file. This may allow attackers to cause a Denial of Service or execute arbitrary code. The issue has been acknowledged and fixed by the vendor. |
