Descriptions

The 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 a lack of input validation checking mechanisms during certain mail parsing operations (mbox.c operations on bounce messages). If successfully exploited, the ClamAV software could allow a variable pointing to the mail body which could cause a used after being free (use-after-free) instance which may lead to a disruption of services on an affected device to include a denial of service 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 la falta de mecanismos de comprobación de validación de entradas durante ciertas operaciones de análisis de email (operaciones mbox.c en mensajes devueltos). Si se explota con éxito, ClamAV podría permitir que una variable que señale al cuerpo del email provoque una instancia de uso de memoria previamente liberada (use-after-free). Esto podría conducir a una interrupción de servicios en el dispositivo afectado para incluir una condición de denegación de servicio (DoS).
