XEmacs JPEG buffer overflow
| xemacs-jpeg-bo (51334) |  High Risk |
Description:
XEmacs is vulnerable to a heap-based buffer overflow, caused by an integer overflow in the jpeg_instantiate() function within glyphs-eimage.c. By persuading a victim to open a specially-crafted JPEG file, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
