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.
