Descriptions

A Denial-of-Service (DoS) vulnerability was discovered in F-Secure & WithSecure products whereby the aegen.dll will go into an infinite loop when unpacking PE files. This eventually leads to scanning engine crash. The exploit can be triggered remotely by an attacker.

Se ha detectado una vulnerabilidad de denegación de servicio (DoS) en los productos F-Secure y WithSecure por la que el archivo aegen.dll entra en un bucle infinito cuando desempaqueta archivos PE. Esto conlleva finalmente a un bloqueo del motor de escaneo. La explotación puede ser desencadenada remotamente por un atacante.
