From secunia security advisory at $URL: Description 1) An error within the handling of email addresses containing certain UTF-8 encoded characters can be exploited to e.g. impersonate another user. 2) The application allows users to perform certain actions via HTTP requests without performing proper validity checks to verify the requests. This can be exploited to e.g. change certain bug data or execute certain administrative tasks when a logged-in user visits a specially crafted web page. Please see the vendor's advisory for a list of affected versions. Solution: Update to version 3.4.14, 3.6.8, or 4.0.4.
3.6.8 is in gentoo-x86 now.
