More information:

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 Pynn├Ânen discovered a cross-site scripting vulnerability, which could enable commenters to compromise a site.
