DESCRIPTION:
A weakness has been reported in MediaWiki, which can be exploited by
malicious users to disclose certain sensitive information.

The weakness is caused due to an error within the "execute()"
function (includes/api/ApiQueryRevisions.php), which discloses old
revision content and can be exploited to disclose deleted cached
content by diffing to a hidden revision.

Successful exploitation requires that the content is cached by a
caching server.

The weakness is reported in versions prior to 1.18.1 and 1.17.2.

SOLUTION:
Update to version 1.18.1 or 1.17.2.

PROVIDED AND/OR DISCOVERED BY:
Roan Kattouw in a bug report.
