Detail

Synopsis

Multiple vulnerabilities in ClamAV allow for the remote execution of arbitrary code or Denial of Service.

Background

Clam AntiVirus (short: ClamAV) is an anti-virus toolkit for UNIX, designed especially for e-mail scanning on mail gateways.

Description

Multiple vulnerabilities have been found in ClamAV:

* The vendor reported a Divide-by-zero error in the PE ("Portable Executable"; Windows .exe) file handling of ClamAV (CVE-2008-6680).

* Jeffrey Thomas Peckham found a flaw in libclamav/untar.c, possibly resulting in an infinite loop when processing TAR archives in clamd and clamscan (CVE-2009-1270).

* Martin Olsen reported a vulnerability in the CLI_ISCONTAINED macro in libclamav/others.h, when processing UPack archives (CVE-2009-1371).

* Nigel disclosed a stack-based buffer overflow in the "cli_url_canon()" function in libclamav/phishcheck.c when processing URLs (CVE-2009-1372).

Impact

A remote attacker could entice a user or automated system to process a specially crafted UPack archive or a file containing a specially crafted URL, possibly resulting in the remote execution of arbitrary code with the privileges of the user running the application, or a Denial of Service. Furthermore, a remote attacker could cause a Denial of Service by supplying a specially crafted TAR archive or PE executable to a Clam AntiVirus instance.

Workaround

There is no known workaround at this time.

Resolution

All Clam AntiVirus users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose =app-antivirus/clamav-0.95.2

Title: DSA-1771-1 clamav -- several
Description: Several vulnerabilities have been discovered in the ClamAV anti-virus toolkit: CVE-2008-6680 Attackers can cayse a denial of service via a crafted EXE file that triggers a divide-by-zero error. CVE-2009-1270 Attackers can cause a denial of service via a crafted tar file that causes clamd and clamscan to hang. Attackers can cause a denial of service via a crafted EXE file that crashes the UPack unpacker. For the old stable distribution, these problems have been fixed in version 0.90.1dfsg-4etch19. For the stable distribution, these problems have been fixed in version 0.94.dfsg.2-1lenny2. For the unstable distribution, these problems have been fixed in version 0.95.1+dfsg-1. We recommend that you upgrade your clamav packages.
