Mozilla Firefox stroke-width buffer overflow

firefox-strokewidth-bo (32698) The risk level is classified as HighHigh Risk

Description:

Mozilla Firefox is vulnerable to a heap-based buffer overflow, caused by improper bounds checking by the _cairo_pen_init function. By creating a specially-crafted SVG file with a large stroke-width attribute in the clipPath element, a remote attacker could overflow a buffer and execute arbitrary code on the system, if the attacker could persuade the victim to view the malicious file.
