Description Josh Bressers 2004-10-07 16:48:30 UTC 
This issue was reported to bugtraq on 2004-09-15
http://www.securityfocus.com/archive/1/375370

Bad array parsing in the rfc1867.c file could lead to the overwriting
of the $_FILES array, which in turn could allow an attacker to write
arbitrary files with the permission of the user running apache.

This issue also affects RHEL2.1

OK.  This is a (somewhat) subtle trick to bypass the sanity checking
of the filename used for the uploaded file.

But the code to do sanity checking of the filename was itself not
added until after 4.3.2, so in fact no clever tricks are needed at all
for this version.
