Red Hat Linux Advisory: httpd

Red Hat Security Advisory

1. Topic:

Updated httpd packages that fix two security issues are now
available for Red Hat Linux 8.0 and 9.

2. Relevant releases/architectures:

Red Hat Linux 8.0 – i386
Red Hat Linux 9 – i386

3. Problem description:

The Apache HTTP server is a powerful, full-featured, efficient,
and freely-available Web server.

A bug in Apache 2.0 through 2.0.45 allows remote attackers to
cause a denial of service, and may allow execution of arbitrary
code. This bug affects both Red Hat Linux 8.0 and 9. The Common
Vulnerabilities and Exposures project (cve.mitre.org/) has assigned the name
CAN-2003-0245 to this issue.

A build system problem in Apache 2.0 through 2.0.45 allows
remote attackers to cause a denial of access to authenticated
content when a threaded server is used. This bug affects only Red
Hat Linux 9 when the threaded server “httpd.worker” has been
configured, which is not the default. The Common Vulnerabilities
and Exposures project (cve.mitre.org/) has assigned the name
CAN-2003-0189 to this issue.

All users of the Apache HTTP Web Server are advised to upgrade
to the applicable errata packages, which contain back-ported fixes
correcting these issues, and applied to Apache version 2.0.40.

After the errata packages are installed, restart the Web service
by running the following command:

/sbin/service httpd restart

Red Hat would like to thank iDefense who initially discovered
CAN-2003-0245 and John Hughes for CAN-2003-0189.

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

7. Verification:

These packages are GPG signed by Red Hat for security. Our key
is available at http://www.redhat.com/solutions/security/news/publickey/

You can verify each package with the following command:

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:

md5sum <filename>
