Detail

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.

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"

Title: DSA-1680 clamav -- buffer overflow, stack consumption
Description: Moritz Jodeit discovered that ClamAV, an anti-virus solution, suffers from an off-by-one-error in its VBA project file processing, leading to a heap-based buffer overflow and potentially arbitrary code execution (>CVE-2008-5050). Ilja van Sprundel discovered that ClamAV contains a denial of service condition in its JPEG file processing because it does not limit the recursion depth when processing JPEG thumbnails (CVE-2008-5314).
