Synopsis

The remote Fedora host is missing a security update.

Description

http://www.mediawiki.org/wiki/Release_notes/1.23#MediaWiki_1.23.7

- (bug 66776, bug 71478) SECURITY: User PleaseStand reported a way to inject code into API clients that used format=php to process pages that underwent flash policy mangling. This was fixed along with improving how the mangling was done for format=json, and allowing sites to disable the mangling using $wgMangleFlashPolicy.

- (bug 70901) SECURITY: User Jackmcbarn reported that the ability to update the content model for a page could allow an unprivileged attacker to edit another user's common.js under certain circumstances. The user right 'editcontentmodel' was added, and is needed to change a revision's content model.

- (bug 71111) SECURITY: User PleaseStand reported that on wikis that allow raw HTML, it is not safe to preview wikitext coming from an untrusted source such as a cross-site request. Thus add an edit token to the form, and when raw HTML is allowed, ensure the token is provided before showing the preview. This check is not performed on wikis that both allow raw HTML and anonymous editing, since there are easier ways to exploit that scenario.

- (bug 72222) SECURITY: Do not show log action when the entry is revdeleted with DELETED_ACTION. NOTICE: this may be reverted in a future release pending a public RFC about the desired functionality. This issue was reported by user Bawolff.

- (bug 71621) Make allowing site-wide styles on restricted special pages a config option.

- (bug 42723) Added updated version history from 1.19.2 to 1.22.13

- $wgMangleFlashPolicy was added to make MediaWiki's mangling of anything that might be a flash policy directive configurable.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected mediawiki package.
