CVE-2017-12375

Estado: ModificadaAlta (7.5)—

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 functions (the rfc2047 function in mbox.c). An unauthenticated, remote attacker could exploit this vulnerability by sending a crafted email to the affected device. This action could cause a buffer overflow condition when ClamAV scans the malicious email, allowing the attacker to potentially cause a DoS condition on an affected device.

CVSS

Probabilidad de explotación (EPSS)

La vulnerabilidad se debe a la falta de mecanismos de comprobación de validación de entradas durante ciertas funciones de análisis de email (la función rfc2047 en mbox.c). 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 cuando ClamAV escanea el email malicioso, permitiendo que el atacante cree una condición de DoS en un dispositivo afectado."
