[Description Alex Xu (Hello71) 2013-11-14 22:11:37 UTC]

I would like to announce the release of MediaWiki 1.21.3, 1.20.8 and
1.19.9. These releases fix 2 security related bugs that could affect users
of MediaWiki. Download links are given at the end of this email.

* Kevin Israel (Wikipedia user PleaseStand) identified and reported two
vectors for injecting Javascript in CSS that bypassed MediaWiki's blacklist
(CVE-2013-4567, CVE-2013-4568).
<https://bugzilla.wikimedia.org/show_bug.cgi?id=55332>

* Internal review while debugging a site issue discovered that MediaWiki
and the CentralNotice extension were incorrectly setting cache headers when
a user was autocreated, causing the user's session cookies to be cached,
and returned to other users (CVE-2013-4572).

Additionally, the following extensions have been updated to fix security
issues:

* CleanChanges: MediaWiki steward Teles reported that revision-deleted IP's
are not correctly hidden when this extension is used (CVE-2013-4569).
