Posted by Team   
RedHat Linux A buffer overflow in Webalizer versions prior to 2.01-10, when configured to use reverse DNS lookups, may allow remote attackers to execute arbitrary code by connecting to the monitored Web server from an IP address that resolves to a long hostname.

                   Red Hat, Inc. Red Hat Security Advisory

Synopsis:          Updated Webalizer packages fix vulnerability
Advisory ID:       RHSA-2002:254-05
Issue date:        2002-12-04
Updated on:        2002-12-04
Product:           Red Hat Linux
Keywords:          DNS resolver buffer overflow flaw:buf
Cross references:  
Obsoletes:         RHSA-2001:140
CVE Names:         CAN-2002-0180

1. Topic:

Updated Webalizer packages which fix an obscure buffer overflow bug in the
DNS resolver code are available for Red Hat Linux 7.2.

2. Relevant releases/architectures:

Red Hat Linux 7.2 - i386, ia64

3. Problem description:

The Webalizer is a Web server log file analysis program which produces 
detailed usage reports in HTML format.
A buffer overflow in Webalizer versions prior to 2.01-10, when configured
to use reverse DNS lookups, may allow remote attackers to execute arbitrary
code by connecting to the monitored Web server from an IP address that
resolves to a long hostname.

Red Hat Linux 7.2 shipped with Webalizer 2.01-9 which is vulnerable to this

Users of webalizer on Red Hat Linux 7.2 are advised to upgrade to these
errata packages which contain Webalizer version 2.01-09 with backported
security and bug fix patches.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade.  Only those
RPMs which are currently installed will be updated.  Those RPMs which are
not installed but included in the list will not be updated.  Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
desired RPMs.

Please note that this update is also available via Red Hat Network.  Many
people find this an easier way to apply updates.  To use Red Hat Network,
launch the Red Hat Update Agent with the following command:


This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.

5. Bug IDs fixed  (http://bugzilla.Red for more info):

60295 - Webalizer configuration file error
64392 - dns_cache missing, preventing webalizer from running

6. RPMs required:

Red Hat Linux 7.2:




7. Verification:

MD5 sum                          Package Name
09943eb2e39f5ed617bb40a5e9b05e39 7.2/en/os/SRPMS/webalizer-2.01_09-1.72.src.rpm
f3d16a9fa3c202031a6cda1da2944e3d 7.2/en/os/i386/webalizer-2.01_09-1.72.i386.rpm
4f225355bff421a2de0b1634d6c54db5 7.2/en/os/ia64/webalizer-2.01_09-1.72.ia64.rpm

These packages are GPG signed by Red Hat, Inc. for security.  Our key
is available at  http://www.Red

You can verify each package with the following command:
    rpm --checksig -v 

If you only wish to verify that each package has not been corrupted or
tampered with, examine only the md5sum with the following command:
