Detail

Synopsis

Multiple vulnerabilities in ClamAV may result in 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

Hanno boeck reported an error in libclamav/chmunpack.c when processing CHM files (CVE-2008-1389). Other unspecified vulnerabilites were also reported, including a NULL pointer dereference in libclamav
(CVE-2008-3912), memory leaks in freshclam/manager.c (CVE-2008-3913), and file descriptor leaks in libclamav/others.c and libclamav/sis.c
(CVE-2008-3914).

Impact

A remote attacker could entice a user or automated system to scan a specially crafted CHM, possibly resulting in a Denial of Service
(daemon crash). The other attack vectors mentioned above could also result in 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"

Title: DSA-1660 clamav -- null pointer dereference, resource exhaustion
Description: Several denial-of-service vulnerabilities have been discovered in the ClamAV anti-virus toolkit: Insufficient checking for out-of-memory conditions results in null pointer dereferences (CVE-2008-3912). Incorrect error handling logic leads to memory leaks (CVE-2008-3913) and file descriptor leaks (CVE-2008-3914).
