Description of problem:
using addhandler for php has very unexpected behavior that can lead to really bad security problems.  addhandler matches the extension anywhere in the filename, so foo.php.jpg will be run as php code.

Version-Release number of selected component (if applicable):
all in rhel5

How reproducible:
always

Steps to Reproduce:
1. create file foo.php.jpg with php code as contents and place in web accessible directory
2. visit appropriate url to access file
3. 
  
Actual results:
php code is run and html displayed

Expected results:
malformed image, php code displayed as text, something else, but not running it as php

Additional info:
this has major implications for web apps that allow uploads into web folders for things like images, pdf files, etc.  expecting that anything.jpg is safe.

see:
http://httpd.apache.org/docs/2.0/mod/mod_mime.html#multipleext
for info about multiple extensions.

a better way to activate php is:

<FilesMatch \.php$>
SetHandler php5-script
ForceType text/html
</FilesMatch>
