A security concern has been fixed in PHP 5.4.0 according to the changelog at [1]. The upstream bug at $URL is currently private. [1] http://www.php.net/ChangeLog-5.php#5.4.0
It looks like this issue was reported in version 5.3.8 according to what information I can see in the upstream bug header.
Fixed in 5.4.0 For 5.3, it has been committed to 5.3 HEAD [1], but no release yet. Upstream release is on its way though. [1] http://git.php.net/?p=php-src.git;a=commit;h=95dcd799fb6fdccbc60d3bba3cd759f6b421ee69

CVE-2012-1172 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-1172): 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.
