Php · Php · CVE-2009-4017
**Name of the Vulnerable Software and Affected Versions**
PHP versions prior to 5.2.12
PHP versions 5.3.x prior to 5.3.1
**Description**
The issue allows remote attackers to cause a denial of service due to resource exhaustion by creating multiple temporary files when handling a multipart/form-data POST request. This also makes it easier for remote attackers to exploit local file inclusion vulnerabilities via multiple requests, related to the lack of support for the `max file uploads` directive.
**Recommendations**
For PHP versions prior to 5.2.12, update to version 5.2.12 or later.
For PHP versions 5.3.x prior to 5.3.1, update to version 5.3.1 or later.
