3. Problem description:
The Apache HTTP Web Server is a secure, efficient, and extensible web
server that provides HTTP services.
Buffer overflows in the ApacheBench support program (ab.c) in Apache
versions prior to 1.3.27, and Apache versions 2.x prior to 2.0.43, allow a
malicious Web server to cause a denial of service (DoS) and possibly
execute arbitrary code via a long response. The Common Vulnerabilities and
Exposures project has assigned the name CAN-2002-0843 to this issue.
Two cross-site scripting (XSS) vulnerabilities are present in the error
pages for the default "404 Not Found" error and for the error response
when a plain HTTP request is received on an SSL port. Both of these issues
are only exploitable if the "UseCanonicalName" setting has been changed to
"Off", and wildcard DNS is in use. These issues could allow remote
attackers to execute scripts as other webpage visitors, for instance, to
steal cookies. These issues affect versions of Apache 1.3 before 1.3.26,
versions of Apache 2.0 before 2.0.43, and versions of mod_ssl before
2.8.12. (CAN-2002-0840, CAN-2002-1157)
The shared memory scoreboard in the HTTP daemon for Apache 1.3, prior to
version 1.3.27, allows a user running as the "apache" UID to send a
SIGUSR1 signal to any process as root, resulting in a denial of service
(process kill) or other such behavior that would not normally be allowed.
(CAN-2002-0839). Note that this issue does not affect Red Hat
Linux 8.0.
All users of the Apache HTTP Web Server are advised to upgrade to the
applicable errata packages. For Red Hat Linux 6.2, 7, 7.1, 7.2, and 7.3,
these packages include Apache version 1.3.27 which is not vulnerable to
these issues. For Red Hat Linux 8.0, the fixes have been back-ported and
applied to Apache version 2.0.40.
Note that the instructions in the "Solution" section of this errata contain
additional steps required to complete the upgrade process.
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.
After the errata packages are installed, restart the Web service by running
the following command:
/sbin/service httpd restart
