Descriptions

Use-after-free vulnerability in the CSharedStyleSheet::Notify function in the Cascading Style Sheets (CSS) parser in mshtml.dll, as used in Microsoft Internet Explorer 6 through 8 and other products, allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a self-referential @import rule in a stylesheet, aka "CSS Memory Corruption Vulnerability."

Vulnerabilidad de uso después de liberación en la función CSharedStyleSheet::Notify en el parseado Cascading Style Sheets (CSS) en mshtml.dll, como el usado en Microsoft Internet Explorer v7 y v8 y probablemente otros productos, permite a atacantes remotos causar una denegación de servicio (caída) y ejecutar código de su elección a través de multiples llamdas @import en un documento manipulado.
