This script is Copyright (C) 2006-2015 Tenable Network Security, Inc.


Synopsis :

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

Description :

The remote host is affected by the vulnerability described in GLSA-200603-22
(PHP: Format string and XSS vulnerabilities)

Stefan Esser of the Hardened PHP project has reported a few
vulnerabilities found in PHP:
Input passed to the session
ID in the session extension isn't properly sanitised before being
returned to the user via a 'Set-Cookie' HTTP header, which can contain
arbitrary injected data.
A format string error while
processing error messages using the mysqli extension in version 5.1 and
above.

Impact :

By sending a specially crafted request, a remote attacker can
exploit this vulnerability to inject arbitrary HTTP headers, which will
be included in the response sent to the user. The format string
vulnerability may be exploited to execute arbitrary code.

Workaround :

There is no known workaround at this time.
