PHP 5.4.x < 5.4.0 Multiple Vulnerabilities

high Nessus Plugin ID 122590


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


According to its banner, the version of PHP installed on the remote host is 5.4.x earlier than 5.4.0, and, therefore, potentially affected by multiple vulnerabilities :

- crypt_blowfish as used in PHP does not properly handle 8-bit characters, which makes it easier for context-dependent attackers to determine a cleartext password by leveraging knowledge of a password hash.

- Multiple NULL Pointer Dereference with the zend_strndup() fucntion could allow a remote attacker to cause a denial of service. (CVE-2011-4153)

- A flaw in SSL sockets with SSL 3.0 / TLS 1.0 was addressed. (CVE-2011-3389)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.


Upgrade to PHP version 5.4.0 or later.
