21 Nov 2019 — 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 C... • https://bugzilla.clamav.net/show_bug.cgi?id=12380 • CWE-20: Improper Input Validation CWE-400: Uncontrolled Resource Consumption •

27 Mar 2019 — ClamAV versions prior to 0.101.2 are susceptible to a denial of service (DoS) vulnerability. An out-of-bounds heap read condition may occur when scanning PE files. An example is Windows EXE and DLL files that have been packed using Aspack as a result of inadequate bound-checking. Las versiones anteriores a la versión 0.101.2 de ClamAV, son susceptibles a una vulnerabilidad de denegación de servicio (DoS). Una condición de lectura de la pila fuera de límites puede presentarse al escanear archivos PE. • https://blog.clamav.net/2019/03/clamav-01012-and-01003-patches-have.html • CWE-20: Improper Input Validation CWE-125: Out-of-bounds Read •

09 Jul 2018 — ClamAV before 0.100.1 lacks a PDF object length check, resulting in an unreasonably long time to parse a relatively small file. ClamAV en versiones anteriores a la 0.100.1 carece de una comprobación de longitud de objeto, lo que resulta en un tiempo demasiado largo para analizar un archivo relativamente pequeño. USN-3722-1 fixed vulnerabilities in ClamAV. The new package introduced an issue which caused dpkg-reconfigure to enter an infinite loop. This update fixes the problem. • http://www.securitytracker.com/id/1041367 • CWE-20: Improper Input Validation •
