Descriptions

The counterToCSSValue function in CSSComputedStyleDeclaration.cpp in the Cascading Style Sheets (CSS) implementation in WebCore in WebKit before r82222, as used in Google Chrome before 11.0.696.43 and other products, does not properly handle access to the (1) counterIncrement and (2) counterReset attributes of CSSStyleDeclaration data provided by a getComputedStyle method call, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via crafted JavaScript code.

La función counterToCSSValue en CSSComputedStyleDeclaration.cpp en las Hojas de Estilo en Cascada (CSS) implementada en WebCore en WebKit anterior a r82222, tal como se usa en Google Chrome anterior a v11.0.696.43 y otros productos, no controla correctamente el acceso a los atributos counterIncrement (1) y (2) counterReset de CSSStyleDeclaration proporcionado por una llamada al método getComputedStyle, permitiendo a atacantes remotos provocar una denegación de servicio (desreferencia a puntero NULL y caída de la aplicación) a través de código JavaScript manipulado.
