medium Nessus Plugin ID 51439
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 a denial of service vulnerability.


According to its banner, the version of PHP 5.x installed on the remote host is older than 5.2.17 or 5.3.5.

Such versions may experience a crash while performing string to double conversion for certain numeric values. Only x86 32-bit PHP processes are known to be affected by this issue regardless of whether the system running PHP is 32-bit or 64-bit.


Upgrade to PHP 5.2.17/5.3.5 or later.
