Flere fejl er opdaget i Clam AntiVirus, antivirusscanningsprogrammet til Unix, der er designet med det formål at kunne integreres med mailservere for at kunne scanne vedhæftede filer. Der er fundet frem til følgende problemer:

CAN-2005-2450
Neel Mehta og Alex Wheeler opdagede at Clam AntiVirus er sårbar over for et heltalsoverløb ved håndtering af filformaterne TNEF, CHM og FSG.
CVE-NOMATCH
Mark Pizzolato rettede en mulig uendelig løkke der kunne forårsage et lammelsesangreb (denial of service).

Den gamle stabile distribution (woody) er ikke påvirket da den ikke indeholder clamav.

I den stabile distribution (sarge) er disse problemer rettet i version 0.84-2.sarge.2.

I den ustabile distribution (sid) er disse problemer rettet i version 0.86.2-1.

Vi anbefaler at du opgraderer din clamav-pakke.
