Summary
Red Hat Security Advisory: apache security update
Notes
Topic
Updated Apache packages that fix a minor security issue are now available
for Red Hat Enterprise Linux.
Details
The Apache HTTP server is a powerful, full-featured, efficient, and
freely-available Web server.
An issue in the handling of regular expressions from configuration files
was discovered in releases of the Apache HTTP Server version 1.3 prior to
1.3.29. To exploit this issue an attacker would need to have the ability
to write to Apache configuration files such as .htaccess or httpd.conf. A
carefully-crafted configuration file can cause an exploitable buffer
overflow and would allow the attacker to execute arbitrary code in the
context of the server (in default configurations as the 'apache' user).
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2003-0542 to this issue.
This update also includes an alternative version of the httpd binary which
supports setting the MaxClients configuration directive to values above 256.
All users of the Apache HTTP Web Server are advised to upgrade to the
applicable errata packages, which contain back-ported fixes correcting
the above security issue.
Note that the instructions in the "Solution" section of this errata contain
additional steps required to complete the upgrade process.

Only those\nRPMs which are currently installed will be updated. Those RPMs which are\nnot installed but included in the list will not be updated. Note that you\ncan also use wildcards (*.rpm) if your current directory *only* contains the\ndesired RPMs.\n\nPlease note that this update is also available via Red Hat Network. Many\npeople find this an easier way to apply updates. To use Red Hat Network,\nlaunch the Red Hat Update Agent with the following command:\n\nup2date\n\nThis will start an interactive process that will result in the appropriate\nRPMs being upgraded on your system.\n\nIf up2date fails to connect to Red Hat Network due to SSL\nCertificate Errors, you need to install a version of the\nup2date client with an updated certificate. The latest version of\nup2date is available from the Red Hat FTP site and may also be\ndownloaded directly from the RHN website:\n\nhttps://rhn.redhat.com/help/latest-up2date.pxt\n\nAfter the errata packages are installed, restart the Web service by running\nthe following command as root:\n\n/sbin/service httpd restart",
