A vulnerability has been reported in the Yoono extension for Firefox, which can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to DOM event handlers being evaluated within the "chrome:" context. This can be exploited to e.g. execute arbitrary commands on a user's system when a user invokes the extension on a specially crafted web page.
The vulnerability is reported in versions prior to 6.1.1.
Solution: Update to version 6.1.1 or later.
