RedHat: webalizer buffer overflow vulnerability
Summary
Summary
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 configuredto use reverse DNS lookups, may allow remote attackers to execute arbitrarycode by connecting to the monitored Web server from an IP address thatresolves to a long hostname.Red Hat Linux 7.2 shipped with Webalizer 2.01-9 which is vulnerable to thisissue.Users of webalizer on Red Hat Linux 7.2 are advised to upgrade to theseerrata packages which contain Webalizer version 2.01-09 with backportedsecurity 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.
