CVE-2017-12379

Estado: ModificadaCrítica (9.8)—

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 or potentially execute arbitrary code on an affected device. The vulnerability is due to improper input validation checking mechanisms in the message parsing function on an affected system. An unauthenticated, remote attacker could exploit this vulnerability by sending a crafted email to the affected device. This action could cause a messageAddArgument (in message.c) buffer overflow condition when ClamAV scans the malicious email, allowing the attacker to potentially cause a DoS condition or execute arbitrary code on an affected device.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

La vulnerabilidad se debe a errores en los mecanismos de comprobación de validación de entradas en la función de análisis de mensajes en un dispositivo afectado. Un atacante remoto no autenticado podría explotar esta vulnerabilidad enviando un email manipulado a un dispositivo afectado. Esta acción podría provocar una condición de desbordamiento de búfer en messageAddArgument (en message.c) cuando ClamAV escanea el email malicioso, permitiendo que el atacante cree una condición de DoS o ejecute código arbitrario en un dispositivo afectado."
