Security Advisory   Security Advisory


*Details:*

Updated httpd packages that include a security fix for mod_ssl and various
enhancements are now available.

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

An input filter bug in mod_ssl was discovered in Apache httpd version
2.0.50 and earlier. A remote attacker could force an SSL connection to be
aborted in a particular state and cause an Apache child process to enter an
infinite loop, consuming CPU resources. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CAN-2004-0748 to
this issue.

Additionally, this update includes the following enhancements and bug fixes:

- included an improved version of the mod_cgi module that correctly handles
concurrent output on stderr and stdout

- included support for direct lookup of SSL variables using %{SSL:...}
from mod_rewrite, or using %{...}s from mod_headers

- restored support for use of SHA1-encoded passwords

- added the mod_ext_filter module

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.
