Cross references:=20=20 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=20 detailed usage reports in HTML format. =20 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. 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: up2date This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. 5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info): 60295 - Webalizer configuration file error 64392 - dns_cache missing, preventing webalizer from running 6. RPMs required: Red Hat Linux 7.2: SRPMS: ftp://updates.redhat.com/7.2/en/os/SRPMS/webalizer-2.01_09-1.72.src.rpm i386: ftp://updates.redhat.com/7.2/en/os/i386/webalizer-2.01_09-1.72.i386.rpm ia64: ftp://updates.redhat.com/7.2/en/os/ia64/webalizer-2.01_09-1.72.ia64.rpm 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.redhat.com/about/contact/pgpkey.html You can verify each package with the following command: =20=20=20=20 rpm --checksig -v <filename> If you only wish to verify that each package has not been corrupted or tampered with, examine only the md5sum with the following command: =20=20=20=20 md5sum <filename> 8.
