[Systems] [Fwd: [MediaWiki-announce] MediaWiki security update: 1.15.4 and 1.16.0beta3]

[Bernie Innocenti]

I think we don't need to worry about these vulnerabilities, but it would
be great if someone could take the time to upgrade our wikis.

Our setup is a little complicated and there's no documentation yet: I
suggest doing the devel and test wikis first, to make some practice.

This is a security and bugfix release of MediaWiki 1.15.4 and
MediaWiki 1.16 beta 3.

Two security vulnerabilities were discovered.

Kuriaki Takashi discovered an XSS vulnerability in MediaWiki. It
affects Internet Explorer clients only. The issue is presumed to
affect all recent versions of IE, it has been confirmed on IE 6 and 8.

Noncompliant CSS parsing behaviour in Internet Explorer allows
attackers to construct CSS strings which are treated as safe by
previous versions of MediaWiki, but are decoded to unsafe strings by
Internet Explorer. Full details can be found at:
https://bugzilla.wikimedia.org/show_bug.cgi?id=23687

A CSRF vulnerability was discovered in our login interface. Although
regular logins are protected as of 1.15.3, it was discovered that the
account creation and password reset features were not protected from
CSRF. This could lead to unauthorised access to private wikis. See
https://bugzilla.wikimedia.org/show_bug.cgi?id=23371 for details.

These vulnerabilities are serious and all users are advised to
upgrade. Remember that CSRF and XSS vulnerabilities can be used even
against firewall-protected intranet installations, as long as the
attacker can guess the URL.

In addition to the security fix, MediaWiki 1.16 beta 3 also contains
many useful bug fixes to 1.16 beta 2. We expect to be able to do a
stable release of the 1.16 branch within the next week or two.

Both releases contain localisation updates courtesy of translatewiki.net.
