PHP Security Bypass and DoS Vulnerabilities
http://www.php.net/releases/5_3_1.php

Added "max_file_uploads" INI directive, which can be set to limit the number of file uploads per-request to 20 by default, to prevent possible DOS via temporary file exhaustion. Added missing sanity checks around exif processing. Fixed a safe_mode bypass in tempnam(). Fixed a open_basedir bypass in posix_mkfifo(). Fixed bug #50063 (safe_mode_include_dir fails). Fixed bug #44683 (popen crashes when an invalid mode is passed).
