In Mitre's CVE dictionary: CVE-2005-2450.

More information:

Several bugs were discovered in Clam AntiVirus, the antivirus scanner for Unix, designed for integration with mail servers to perform attachment scanning. The following problems were identified:

CAN-2005-2450
Neel Mehta and Alex Wheeler discovered that Clam AntiVirus is vulnerable to integer overflows when handling the TNEF, CHM and FSG file formats.
CVE-NOMATCH
Mark Pizzolato fixed a possible infinite loop that could cause a denial of service.

The old stable distribution (woody) is not affected as it doesn't contain clamav.

For the stable distribution (sarge) these problems have been fixed in version 0.84-2.sarge.2.

For the unstable distribution (sid) these problems have been fixed in version 0.86.2-1.

We recommend that you upgrade your clamav package.

Fixed in:

Debian GNU/Linux 3.1 (sarge)
