Descriptions

The layout engine in Mozilla Firefox 3.x before 3.0.5 and 2.x before 2.0.0.19, Thunderbird 2.x before 2.0.0.19, and SeaMonkey 1.x before 1.1.14 allows remote attackers to cause a denial of service (crash) and possibly trigger memory corruption via vectors related to (1) a reachable assertion or (2) an integer overflow.

El motor de diseño de Mozilla Firefox 3.x anterior a 3.0.5 y 2.x anterior a 2.0.0.19, Thunderbird 2.x anterior a 2.0.0.19 y SeaMonkey 1.x anterior a 1.1.14, permite a atacantes remotos provocar una denegación de servicio (caída) y probablemente provocar una corrupción de memoria a través de vectores relacionados con (1) un fallo de aserción o (2) un desbordamiento de entero.

Several flaws were discovered in the Thunderbird browser engine. Boris Zbarsky discovered that the same-origin check in Thunderbird could be bypassed by utilizing XBL-bindings. Marius Schilder discovered that Thunderbird did not properly handle redirects to an outside domain when an XMLHttpRequest was made to a same-origin resource. Chris Evans discovered that Thunderbird did not properly protect a user's data when accessing a same-domain Javascript URL that is redirected to an unparsable Javascript off-site resource. Chip Salzenberg, Justin Schuh, Tom Cross, and Peter William discovered Thunderbird did not properly parse URLs when processing certain control characters. Kojima Hajime discovered that Thunderbird did not properly handle an escaped null character. An attacker may be able to exploit this flaw to bypass script sanitization. Several flaws were discovered in the Javascript engine.
