Descriptions

ClamAV AntiVirus software versions 0.99.2 and prior contain a vulnerability that could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to improper input validation checking mechanisms in mbox.c during certain mail parsing functions of the ClamAV software. An unauthenticated, remote attacker could exploit this vulnerability by sending a crafted email to the affected device. An exploit could trigger a NULL pointer dereference condition when ClamAV scans the malicious email, which may result in a DoS condition.

ClamAV AntiVirus, en versiones 0.99.2 y anteriores, contiene una vulnerabilidad que podría permitir que un atacante remoto sin autenticar provoque una denegación de servicio (DoS) en un sistema afectado. La vulnerabilidad se debe a errores en los mecanismos de comprobación de validación de entradas en mbox.c durante ciertas funciones de análisis de email en un dispositivo afectado. Un atacante remoto no autenticado podría explotar esta vulnerabilidad enviando un email manipulado a un dispositivo afectado. Un exploit podría desencadenar una condición de desreferencia de puntero NULL cuando ClamAV escanea el email malicioso, lo que podría resultar en una condición de DoS.
