 * 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<pipe>off<pipe>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 announcement
can be read here:

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.

Here are the details from the Slackware 10.2 ChangeLog:
+--------------------------+
patches/packages/apache-1.3.34-i486-1.tgz: Upgraded to apache-1.3.34.
 Fixes this minor security bug: 'If a request contains both Transfer-Encoding
 and Content-Length headers, remove the Content-Length, mitigating some HTTP
 Request Splitting/Spoofing attacks.'
 (* Security fix *)
patches/packages/mod_ssl-2.8.25_1.3.34-i486-1.tgz:
 Upgraded to mod_ssl-2.8.25-1.3.34.
+--------------------------+");
