Synopsis :

The remote FreeBSD host is missing one or more security-related

Description :

Secunia reports :

A vulnerability has been reported in ClamAV, which can be exploited by
malicious people to cause a DoS (Denial of Service) and potentially to
compromise a vulnerable system.

The vulnerability is caused due to a boundary error within the HTTP
client in the Freshclam command line utility. This can be exploited to
cause a stack-based buffer overflow when the HTTP headers received
from a web server exceeds 8KB.

Successful exploitation requires that Freshclam is used to download
virus signature updates from a malicious mirror web server e.g. via
DNS poisoning.
