Mozilla Firefox, Thunderbird, and SeaMonkey DOMAttrModified code execution

firefox-domattrmodified-code-exec (71910) The risk level is classified as HighHigh Risk

Description:

Mozilla Firefox, Thunderbird, and SeaMonkey could allow a remote attacker to execute arbitrary code on the system, caused by an error in the SVG implementation related to the removal of SVG elements during a DOMAttrModified event handler. By persuading a victim to visit a specially-crafted Web site, a remote attacker could exploit this vulnerability to trigger an out-of-bounds memory access and execute arbitrary code on the vulnerable system or cause a denial of service.
