Fedora 15 : mediawiki-1.16.5-59.fc15 (2011-6781)

medium Nessus Plugin ID 54572

Language:

Synopsis

The remote Fedora host is missing a security update.

Description

MediaWiki 1.16.5 was released to correct two security flaws :

The first issue is yet another recurrence of the Internet Explorer 6 XSS vulnerability that caused the release of 1.16.4. It was pointed out that there are dangerous extensions with more than four characters, so the regular expressions we introduced had to be updated to match longer extensions. (CVE-2011-1765)

The second issue allows unauthenticated users to gain additional rights, on wikis where $wgBlockDisablesLogin is enabled. By default, it is disabled. The issue occurs when a malicious user sends cookies which contain the user name and user ID of a 'victim' account. In certain circumstances, the rights of the victim are loaded and persist throughout the malicious request, allowing the malicious user to perform actions with the victim's rights. (CVE-2011-1766)

$wgBlockDisablesLogin is a feature which is sometimes used on private wikis to prevent users who have an account from logging in and viewing content on the wiki.

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.
