| タイトル | GPAC 26.03-DEV Buffer Overflow |
|---|
| 説明 | A stack buffer overflow vulnerability exists in GPAC version 26.03-DEV. The issue is located in the function txtin_process_texml() within the file src/filters/load_text.c. The fixed-size stack array GF_StyleRecord styles[50] is accessed via nb_styles index without proper bounds checking. A crafted TeXML file with more than 50 <sharedStyles> blocks causes a stack-based buffer overflow via memset() at line 3844. This vulnerability can lead to Denial of Service (DoS) or potential code execution. The vendor has confirmed and fixed this issue on GitHub. |
