Descriptions

A vulnerability in the OOXML parsing module in Clam AntiVirus (ClamAV) Software version 0.104.1 and LTS version 0.103.4 and prior versions could allow an unauthenticated, remote attacker to cause a denial of service condition on an affected device. The vulnerability is due to improper checks that may result in an invalid pointer read. An attacker could exploit this vulnerability by sending a crafted OOXML file to an affected device. An exploit could allow the attacker to cause the ClamAV scanning process to crash, resulting in a denial of service condition.

Una vulnerabilidad en el módulo de análisis de OOXML en el software Clam AntiVirus (ClamAV) versión 0.104.1 y LTS versiones 0.103.4 y anteriores, podría permitir a un atacante remoto no autenticado causar una condición de denegación de servicio en un dispositivo afectado. La vulnerabilidad es debido a comprobaciones inapropiadas que pueden resultar en una lectura de un puntero no válido. Un atacante podría aprovechar esta vulnerabilidad mediante el envío de un archivo OOXML diseñado a un dispositivo afectado. Una explotación podría permitir al atacante causar el bloqueo del proceso de escaneo de ClamAV, resultando en una condición de denegación de servicio
