ClamAV: Multiple vulnerabilities — GLSA 200812-21

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

Affected Packages

app-antivirus/clamav on all architectures
Affected versions < 0.94.2
Unaffected versions >= 0.94.2

Background

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

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"
