ClamAV: Multiple vulnerabilities

Background

Clam AntiVirus is a free anti-virus toolkit for UNIX, designed especially for e-mail scanning on mail gateways.

Description

An integer overflow has been reported in the “cli_scanpe()” function in file libclamav/pe.c (CVE-2008-0318). Another unspecified vulnerability has been reported in file libclamav/mew.c (CVE-2008-0728).

Impact

A remote attacker could entice a user or automated system to scan a specially crafted file, possibly leading to the execution of arbitrary code with the privileges of the user running ClamAV (either a system user or the “clamav” user if clamd is compromised).

Workaround

There is no known workaround at this time.

Resolution

All ClamAV users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=app-antivirus/clamav-0.92.1"
