DESCRIPTION:
A weakness has been discovered in MediaWiki, which can be exploited
by malicious people to disclose potentially sensitive information.

The weakness is caused due to the "preliminaryChecks()" function
improperly verifying requests when the "curid" parameter is set and
can be exploited to disclose the titles of pages on a private wiki.

NOTE: An additional weakness exists when handling certain AJAX
requests, which can be exploited to identify the presence of a file
on a private wiki by supplying a filename in a request.

The weakness is confirmed in version 1.17.0. Prior versions may also
be affected.

SOLUTION:
Update to version 1.17.1.

PROVIDED AND/OR DISCOVERED BY:
The vendor credits Alexandre Emsenhuber.
