Debian DSA-3085-1 : wordpress - security update

medium Nessus Plugin ID 79696

Synopsis

The remote Debian host is missing a security-related update.

Description

Multiple security issues have been discovered in Wordpress, a web blogging tool, resulting in denial of service or information disclosure. More information can be found in the upstream advisory at

- 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.

Solution

Upgrade the wordpress packages.

For the stable distribution (wheezy), these problems have been fixed in version 3.6.1+dfsg-1~deb7u5.

For the upcoming stable distribution (jessie), these problems have been fixed in version 4.0.1+dfsg-1.
