PHP 5.5.x < 5.5.11 awk Magic Parsing BEGIN DoS

medium Nessus Plugin ID 73411

Language:

Synopsis

The remote web server uses a version of PHP that is potentially affected by a denial of service vulnerability.

Description

According to its banner, the version of PHP 5.5.x installed on the remote host is a version prior to 5.5.11. It is, therefore, potentially affected by a denial of service vulnerability.

A flaw exists in the awk script detector within magic/Magdir/commands where multiple wildcards with unlimited repetitions are used. This could allow a context dependent attacker to cause a denial of service with a specially crafted ASCII file.

Note that this plugin has not attempted to exploit this issue, but has instead relied only on PHP's self-reported version number.

Solution

Upgrade to PHP version 5.5.11 or later.
