Debian DSA-776-1 : clamav - integer overflows, infinite loop

high Nessus Plugin ID 19432

Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

Upgrade the clamav package.

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.
