Soporte de vulnerabilidades

Servicio de soporte de vulnerabilidadesAnálisis, 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. Las vulnerabilidades se describen a continuación:

- CVE-2006-4182: Desbordamiento de entero en ClamAV versiones anteriores a 0.88.5. Un atacante remoto podría causar una denegación de servicio y ejecutar código arbitrario mediante la manipulación de archivos "Portable Executable (PE)" que provocan un desbordamiento de búfer cuando la memoria reservada es menor de la esperada.

- CVE-2006-5295: Una vulnerabilidad no especificada afecta a las versiones anteriores de ClamAV 0.88.5. Un atacante remoto podría causar una denegación de servicio a través de un archivo de ayuda HTML (CHM) especialmente construido produciendo así un acceso de lectura a una región de memoria no válida.
