CLA-2002:476-webalizer

by Nikola Strahija on April 26th, 2002 Spybreak reported a buffer overflow vulnerability in the DNS resolver code. This flaw could possibly be exploited by a remote attacker in control of a DNS server which would be queried by the webalizer program.


Webalizer in Conectiva Linux is not executed by default, it is necessary for the user to configure and enable a cron job for it to run.

SOLUTION
It is recommended that all webalizer users upgrade their packages.
