Mandriva Linux Security Advisory MDKSA-2006-080: Ulf Harnhammar discovered that the freshclam tool does not do a proper check for the size of header data received from a web server. This could potentially allow a specially prepared HTTP server to exploit freshclam clients connecting to a database mirror and causing a DoS. The updated packages have been updated to Clamav 0.88.2 which corrects this problem.
