PHP 5.4.x < 5.4.44 Multiple Vulnerabilities

high Nessus Plugin ID 85298
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 running on the remote web server is 5.4.x prior to 5.4.44. It is, therefore, affected by multiple vulnerabilities:

- Multiple use-after-free vulnerabilities exist in the SPL component, due to improper handling of a specially crafted serialized object. An unauthenticated, remote attack can exploit this, via vectors involving ArrayObject, splObjectStorage and SplDoublyLinkedList to execute arbitrary code. (CVE-2015-6831)

- A use-after-free vulnerability exists in ext/spl/spl_array.c due to improper handling of a specially crafted serialized data. An unauthenticated, remote attacker can exploit this via specially crafted serialized data that triggers misuse of an array field to execute arbitrary code. (CVE-2015-6832)

- A directory traversal vulnerability exists in the PharData class, due to improper implementation of the exctractTo function. An unauthenticated, remote attacker can exploit this via a crafted ZIP archive entry to write to arbitrary files. (CVE-2015-6833)

- The openssl_random_pseudo_bytes() function in file openssl.c does not generate sufficiently random numbers.
An unauthenticated, remote attacker can exploit this to defeat cryptographic protection mechanisms.

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


Upgrade to PHP version 5.4.44 or later.
