A vulnerability in the email parsing module Clam AntiVirus (ClamAV) Software versions 0.102.0, 0.101.4 and prior could allow an unauthenticated, remote attacker to cause a denial of service condition on an affected device. The vulnerability is due to inefficient MIME parsing routines that result in extremely long scan times of specially formatted email files. An attacker could exploit this vulnerability by sending a crafted email file to an affected device. An exploit could allow the attacker to cause the ClamAV scanning process to scan the crafted email file indefinitely, resulting in a denial of service condition. Una vulnerabilidad en el módulo de análisis de correo electrónico de Clam AntiVirus (ClamAV) Software versiones 0.102.0, 0.101.4 y anteriores, podría permitir a un atacante remoto no autenticado causar una condición de denegación de servicio en un dispositivo afectado. • https://bugzilla.clamav.net/show_bug.cgi?id=12380 https://lists.debian.org/debian-lts-announce/2020/02/msg00016.html https://quickview.cloudapps.cisco.com/quickview/bug/CSCvr56010 https://security.gentoo.org/glsa/202003-46 https://usn.ubuntu.com/4230-2 • CWE-20: Improper Input Validation CWE-400: Uncontrolled Resource Consumption •

A vulnerability in the Portable Executable (PE) file scanning functionality of Clam AntiVirus (ClamAV) Software versions 0.101.1 and prior could allow an unauthenticated, remote attacker to cause a denial of service condition on an affected device. The vulnerability is due to a lack of proper input and validation checking mechanisms for PE files sent an affected device. An attacker could exploit this vulnerability by sending malformed PE files to the device running an affected version ClamAV Software. An exploit could allow the attacker to cause an out-of-bounds read condition, resulting in a crash that could result in a denial of service condition on an affected device. Una vulnerabilidad en la funcionalidad de escaneado de archivos ejecutables portátiles (PE) del software Clam AntiVirus (ClamAV) versiones 0.101.1 y anteriores, podría permitir que un atacante remoto no autenticado cause una condición de denegación de servicio en un dispositivo afectado. • https://bugzilla.clamav.net/show_bug.cgi?id=12262 https://security.gentoo.org/glsa/201904-12 • CWE-20: Improper Input Validation CWE-125: Out-of-bounds Read •
