Security Advisory Updated Webalizer packages fix vulnerability

Advisory: RHSA-2002:254-05
Type: Security Advisory
Severity: N/A
Issued on: 2002-12-04
Last updated on: 2002-12-04
Affected Products: Red Hat Linux 7.2
CVEs (cve.mitre.org): CVE-2002-0180

Details

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

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
issue.

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.


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:

up2date

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