http://security.gentoo.org/

Severity:	high
Title:	ClamAV: Multiple vulnerabilities
Date:	12/23/2008
Bugs:	#245450, #249833
ID:	200812-21

Synopsis

Two vulnerabilities in ClamAV may allow for the remote execution of arbitrary code or a Denial of Service.

Background

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

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
app-antivirus/clamav	< 0.94.2	>= 0.94.2	All supported architectures

Description

Moritz Jodeit reported an off-by-one error within the get_unicode_name() function in libclamav/vba_extract.c when processing VBA project files (CVE-2008-5050). Ilja van Sprundel reported an infinite recursion error within the cli_check_jpeg_exploit() function in libclamav/special.c when processing JPEG files (CVE-2008-5314).

Impact

A remote attacker could send a specially crafted VBA or JPEG file to the clamd daemon, possibly resulting in the remote execution of arbitrary code with the privileges of the user running the application or a Denial of Service.

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-0.94.2"
