|Package||www-apps/mediawiki on all architectures|
|Affected versions||< 1.3.11|
|Unaffected versions||>= 1.3.11|
MediaWiki is a collaborative editing software, used by big projects like Wikipedia.
A security audit of the MediaWiki project discovered that MediaWiki is vulnerable to several cross-site scripting and cross-site request forgery attacks, and that the image deletion code does not sufficiently sanitize input parameters.
There is no known workaround at this time.
All MediaWiki users should upgrade to the latest available version:
# emerge --sync # emerge --ask --oneshot --verbose ">=www-apps/mediawiki-1.3.11"
