Tk Toolkit FileReadGIF denial of service
| tktoolkit-filereadgif-dos (37189) |  Low Risk |
Description:
TK is vulnerable to a denial of service, caused by a buffer overflow in the FileReadGIF function. By persuading a victim to open a specially-crafted GIF file in which the first subimage is smaller than the next subimage, a remote attacker could exploit this vulnerability to cause a segmentation fault.
