Amaya HTML tags buffer overflow
|amaya-html-tags-bo (48325)||High Risk|
Amaya is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the EndOfXmlAttributeValue(), EndOfStartGI(), ProcessStartGI() functions when processing input HTML tags. By persuading a victim to visit a specially-crafted Web page with an overly long type parameter in an HTML tag, a remote attacker could exploit this vulnerability to overflow a buffer and execute arbitrary code on the system.
Upgrade to the latest version of Amaya (11.1 or later), available from the W3C Web site. See References.

NOTE: these are different vectors than CVE-2008-6005.
