critical Nessus Plugin ID 90825

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

USN-2952-1 fixed vulnerabilities in PHP. One of the backported patches caused a regression in the PHP Soap client. This update fixes the problem.

We apologize for the inconvenience.
