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.

Bugs

Notes

Author	Note
jdstrand	some argue bug is in script, not the language, but PHP does try to sanitize $_FILES. Script writers may be relying on that.
