Subject: Linux: remote buffer overflow in webalizer reverse lookup code
Advisory number: CSSA-2002-036.0
Issue date: 2002 October 22
Cross reference:

1. Problem Description
The webalizer program will perform reverse DNS lookups. Using
a buffer overflow in this reverse lookup code, an attacker with
a rogue DNS server can gain root access to the machine running
webalizer.
2. Vulnerable Supported Versions
System Package
----------------------------------------------------------------------
OpenLinux 3.1.1 Server prior to webalizer-2.01_09-2.i386.rpm
OpenLinux 3.1 Server prior to webalizer-2.01_09-2.i386.rpm
3. Solution
The proper solution is to install the latest packages. Many
customers find it easier to use the Caldera System Updater, called
cupdate (or kcupdate under the KDE environment), to update these
packages rather than downloading and installing them by hand.
