This indicates an attack attempt to exploit a memory corruption vulnerability
in Mozilla Foundation's family of browser products.
The vulnerability is caused by an error when the vulnerable software handles the document appended with an SVG comment DOM node. It may allow remote attackers to execute arbitrary code in the context of the application. Failed exploit attempts will likely cause the program to crash, resulting in a denial of service condition.
