Soporte de vulnerabilidades

Servicio de soporte de vulnerabilidades Análisis, notificación y seguimiento de aquellas vulnerabilidades más críticas, que impactan especialmente en las tecnologías empleadas en el sector público. El CCN-CERT trabajará en la recopilación y clasificación de las nuevas vulnerabilidades, realizando un análisis teórico y en laboratorio, cuando sea posible, de aquellas que por su criticidad lo requieran.

Se generarán documentos informativos o “abstracts” de dichas vulnerabilidades y se llevará a cabo un seguimiento de la evolución de la vulnerabilidad en Internet, alertando a los organismos ante cambios en la criticidad, aparición de parches, nuevas recomendaciones, constancia de explotaciones activas, etc.

Para inscribirse en este servicio o recibir más información, escribir al correo electrónico: soporte_acreditacion@ccn.cni.es

Descripción
Se han descubierto múltiples vulnerabilidades en ClamAV versiones anteriores a 0.87. Las vulnerabilidades son descritas a continuación: - CAN-2005-2919: Un desbordamiento de entero en "libclamav/upx.c" podría permitir a un atacante remoto no autenticado causar un desbordamiento de búfer y posiblemente la ejecución de comandos arbitrarios, mediante el envío de un fichero ejecutable comprimido UPX especialmente diseñado. - CAN-2005-2920: Un error en "libclamav/fsg.c" podría permitir a un atacante remoto generar un bucle infinito (denegación de servicio) mediante el envío de un fichero ejecutable comprimido FSG especialmente diseñado.
