Title: PHP Improper Input Validation Vulnerability
Overview:

The file-upload implementation in rfc1867.c in PHP before 5.4.0 does not properly handle invalid (open square bracket) characters in name values which makes it easier for remote attackers to cause a denial of service (malformed _FILES indexes) or conduct directory traversal attacks during multi-file uploads by leveraging a script that lacks its own filename restrictions.
