Debian DLA-236-1 : wordpress security update

medium Nessus Plugin ID 83918

Language:

Synopsis

The remote Debian host is missing a security update.

Description

In the Debian squeeze-lts version of Wordpress, multiple security issues have been fixed :

Remote attackers could...

- ... upload files with invalid or unsafe names

- ... mount social engineering attacks

- ... compromise a site via cross-site scripting

- ... inject SQL commands

- ... cause denial of service or information disclosure

CVE-2014-9031

Jouko Pynnonen discovered an unauthenticated cross site scripting vulnerability (XSS) in wptexturize(), exploitable via comments or posts.

CVE-2014-9033

Cross site request forgery (CSRF) vulnerability in the password changing process, which could be used by an attacker to trick an user into changing her password.

CVE-2014-9034

Javier Nieto Arevalo and Andres Rojas Guerrero reported a potential denial of service in the way the phpass library is used to handle passwords, since no maximum password length was set.

CVE-2014-9035

John Blackbourn reported an XSS in the 'Press This' function (used for quick publishing using a browser 'bookmarklet').

CVE-2014-9036

Robert Chapin reported an XSS in the HTML filtering of CSS in posts.

CVE-2014-9037

David Anderson reported a hash comparison vulnerability for passwords stored using the old-style MD5 scheme. While unlikely, this could be exploited to compromise an account, if the user had not logged in after a Wordpress 2.5 update (uploaded to Debian on 2 Apr, 2008) and the password MD5 hash could be collided with due to PHP dynamic comparison.

CVE-2014-9038

Ben Bidner reported a server side request forgery (SSRF) in the core HTTP layer which unsufficiently blocked the loopback IP address space.

CVE-2014-9039

Momen Bassel, Tanoy Bose, and Bojan Slavkovic reported a vulnerability in the password reset process: an email address change would not invalidate a previous password reset email.

CVE-2015-3438

Cedric Van Bockhaven reported and Gary Pendergast, Mike Adams, and Andrew Nacin of the WordPress security team fixed a cross-site-scripting vulnerabilitity, which could enable anonymous users to compromise a site.

CVE-2015-3439

Jakub Zoczek discovered a very limited cross-site scripting vulnerability, that could be used as part of a social engineering attack.

CVE-2015-3440

Jouko Pynnönen discovered a cross-site scripting vulnerability, which could enable commenters to compromise a site.
