PHP 5.3 < 5.3.7 Multiple Vulnerabilities

critical Nessus Plugin ID 55925
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote web server uses a version of PHP that is affected by multiple vulnerabilities.


According to its banner, the version of PHP 5.3.x running on the remote host is prior to 5.3.7. It is, therefore, affected by the following vulnerabilities :

- A use-after-free vulnerability in substr_replace().

- A stack-based buffer overflow in socket_connect().

- A code execution vulnerability in ZipArchive::addGlob().

- crypt_blowfish was updated to 1.2. (CVE-2011-2483)

- Multiple NULL pointer dereferences. (CVE-2011-3182)

- An unspecified crash in error_log(). (CVE-2011-3267)

- A buffer overflow in crypt(). (CVE-2011-3268)

- A flaw exists in the php_win32_get_random_bytes() function when passing MCRYPT_DEV_URANDOM as source to mcrypt_create_iv(). A remote attacker can exploit this to cause a denial of service condition.


Upgrade to PHP 5.3.7 or later.
