Detail

Synopsis

Multiple vulnerabilities have been discovered in ClamAV allowing remote execution of arbitrary code and Denial of Service attacks.

Background

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

Description

iDefense reported an integer overflow vulnerability in the cli_scanpe()
function when parsing Portable Executable (PE) files packed in the MEW format, that could be exploited to cause a heap-based buffer overflow
(CVE-2007-6335). Toeroek Edwin reported an off-by-one error when decompressing MS-ZIP compressed CAB files (CVE-2007-6336). An unspecified vulnerability related to the bzip2 decompression algorithm has also been discovered (CVE-2007-6337).

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).

Workaround

There is no known workaround at this time.

Resolution

All ClamAV users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot -v ">=app-antivirus/clamav-0.91.2-r1"
