Advisory: RHSA-2004:182-03
Type: Security Advisory
Severity: N/A
Issued on: 2004-04-30
Last updated on: 2004-04-30
Affected Products: Red Hat Linux 9
OVAL: N/A
CVEs (cve.mitre.org): CVE-2004-0113

Details

Updated httpd packages are now available that fix a denial of service
vulnerability in mod_ssl and include various other bug fixes.

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

A memory leak in mod_ssl in the Apache HTTP Server prior to version 2.0.49
allows a remote denial of service attack against an SSL-enabled server. The
Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned
the name CAN-2004-0113 to this issue.

Users of the Apache HTTP server should upgrade to these updated packages,
which contain backported patches that address these issues.


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.
