CVE-2012-1172

原文の説明

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.

影響を受けるソフトウェア

• PHP = 5.0.2= 5.1.3= 5.3.9≤ 5.3.10= 5.2.12= 5.3.4 完全一致
