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
-------------------------------------------------------------------=
1 app-antivirus/clamav < 0.94.2 >= 0.94.=2

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="
