CVE-2009-4017 Information

Description

PHP before 5.2.12 and 5.3.x before 5.3.1 does not restrict the number of temporary files created when handling a multipart/form-data POST request which allows remote attackers to cause a denial of service (resource exhaustion) and makes it easier for remote attackers to exploit local file inclusion vulnerabilities via multiple requests related to lack of support for the max_file_uploads directive.
