The results are presented in both columnar and graphical format, which facilitates interpretation. Webalizer 2.01-06 is a part of the Red Hat Linux 7.2 distribution, enabled by default and run daily by the cron daemon. --- PROBLEM --- The webalizer has the ability to perform reverse DNS lookups. This ability is disabled by default, but if enabled, an attacker with command over his own DNS service, has the ability to gain remote root acces to a machine, due to a remote buffer overflow in the reverse resolving code.
