New apache packages are available for Slackware 8.1, 9.0, 9.1, 10.0, 10.1, 10.2, and -current to fix potential security issues:

* If a request contains both Transfer-Encoding and Content-Length headers, remove the Content-Length, mitigating some HTTP Request Splitting/Spoofing attacks.

* Added TraceEnable [on|off|extended] per-server directive to alter the behavior of the TRACE method.

It's hard to say how much real-world impact these have, as there's no more information about that in the announcement. The original Apache nnounement can be read here:

http://www.apache.org/dist/httpd/Announcement1.3.html

Note that if you use mod_ssl, you will also need a new mod_ssl package. These have been provided for the same releases of Slackware.

Installation instructions:
+------------------------+


First, stop apache:

# apachectl stop

Then, upgrade the apache package:

# upgradepkg apache-1.3.34-i486-1.tgz

If you use mod_ssl, you'll also need to upgrade that package. The
upgrade should save the important config files for mod_ssl,
nevertheless it's a good idea to backup any keys/certificates you wish
to save for mod_ssl (in /etc/apache/ssl.*), then upgrade mod_ssl:

# upgradepkg mod_ssl-2.8.25_1.3.34-i486-1.tgz

If necessary, restore any mod_ssl config files.

Finally, restart apache:

# apachectl start

Or, if you use mod_ssl:

# apachectl startssl
