Synopsis

Multiple vulnerabilities in ClamAV may result in the remote execution of arbitrary code.

2. Impact Information

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).

3. Resolution Information

Workaround

There is no known workaround at this time.

Resolution

All ClamAV users should upgrade to the latest version:

Code Listing 3.1: Resolution

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