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.

Affected products and versions

  • PHP — Before 5.2.12
  • PHP versions 5.3.0, 5.3.0alpha1, 5.3.0alpha2, 5.3.0alpha3, 5.3.0beta1, 5.3.0rc1, 5.3.0rc2, 5.3.0rc3, 5.3.0rc4
