MediaWiki 1.16.4 security release

Posted by Rob Lanphier on April 15, 2011

MediaWiki 1.16.4 is a second security release this week. Shortly after previous release (1.16.3), Masato Kinugawa discovered that one of the XSS problems that the 1.16.3 release was designed to address hadn’t been fully addressed, and reported bug 28507. As a consequence, Internet Explorer 6 users visiting a site running 1.16.3 will still be vulnerable to an XSS attack. After more thorough testing (thanks Roan Kattouw!), we’re releasing 1.16.4.

Full details are in Tim Starling’s 1.16.4 release announcement. Sorry for the inconvenience of a second release, and thank you everyone involved in getting this fixed!

MediaWiki 1.16.3 security release

Posted by Rob Lanphier on April 12, 2011

There is a new MediaWiki release available which addresses three security vulnerabilities:

A cross-site scripting (XSS) issue involving media uploads affecting Internet Explorer version 6 and earlier. Note: fully addressing this issue requires web server configuration changes. See bug 28235 and full announcement below for details (discovered by Masato Kinugawa).
A CSS validation problem in the wikitext parser. This is a cross-site scripting (XSS) issue for all Internet Explorer clients, and a privacy loss issue for other clients. See bug 28450 and full announcement below for details (discovered by user Suffusion)
A transwiki import problem with access control checks on form submission, which only affects wikis where this feature is enabled. For more details, see bug 28449 and full announcement below for details (discovered by MediaWiki developer Happy-Melon)

Full announcement from Tim Starling after the jump…
