Secunia Research has discovered a security issue in Opera, which can be exploited by malicious people to compromise a vulnerable system. The "Download" dialog provides the option to run a downloadable executable at a predictable location in the browser window. This can be exploited to trick a user into clicking on the "Run" button by positioning a new window on top of the "Download" dialog that is closed e.g. via a timeout shortly before the user clicks on a link within this window. Versions 10.53, 10.54, and 10.60 are affected.
