Description Vincent Danen 2011-04-13 17:59:47 EDT
Mediawiki 1.16.3 was released [1] to correct three security flaws:

Masato Kinugawa discovered a cross-site scripting (XSS) issue, which
affects Internet Explorer clients only, and only version 6 and
earlier. Web server configuration changes are required to fix this
issue. Upgrading MediaWiki will only be sufficient for people who use
Apache with AllowOverride enabled. (CVE-2011-1578)

Wikipedia user Suffusion of Yellow discovered a CSS validation error
in the wikitext parser. This is an XSS issue for Internet Explorer
clients, and a privacy loss issue for other clients since it allows
the embedding of arbitrary remote images. (CVE-2011-1579)

MediaWiki developer Happy-Melon discovered that the transwiki import
feature neglected to perform access control checks on form submission.
The transwiki import feature is disabled by default. If it is enabled,
it allows wiki pages to be copied from a remote wiki listed in
$wgImportSources. The issue means that any user can trigger such an
import to occur. (CVE-2011-1580)

Comment 4 Vincent Danen 2011-04-14 10:39:39 EDT
1.16.3 is not sufficient, as it does not fully fix the CVE-2011-1578 issue.  Mediawiki 1.16.4 has been released to fully address it: http://lists.wikimedia.org/pipermail/mediawiki-announce/2011-April/000097.html
Comment 5 Vincent Danen 2011-04-18 17:57:46 EDT
