-------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2011-6781 2011-05-09 22:34:50 -------------------------------------------------------------------------------- Name : mediawiki Product : Fedora 15 Version : 1.16.5 Release : 59.fc15 URL : http://www.mediawiki.org/ Summary : A wiki engine Description : MediaWiki is the software used for Wikipedia and the other Wikimedia Foundation websites. Compared to other wikis, it has an excellent range of features and support for high-traffic websites using multiple servers This package supports wiki farms. Read the instructions for creating wiki instances under /usr/share/doc/mediawiki-1.16.5/README.RPM. Remember to remove the config dir after completing the configuration. -------------------------------------------------------------------------------- Update Information: 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. -------------------------------------------------------------------------------- ChangeLog: * Sun May 8 2011 Axel Thimm |
