A security concern has been fixed in PHP 5.4.0 according to the changelog at . The upstream bug at $URL is currently private.
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 , but no release yet. Upstream release is on its way though.

Arches, please test and mark stable:
Target keywords : "alpha amd64 arm hppa ia64 ppc ppc64 s390 sh sparc x86"
x86 stable, thanks.
Stable for HPPA.
Removing arches as we need to work in 414553 instead.
Thanks, everyone. Added to existing GLSA request.
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
