Public keys containing such content are still valid. Therefor they can be distributed and in case the uid field contains javascript code, they can be used to inject code. Risk: Malicious script code can be executed within a users context. This can lead to session hijacking or triggering unwanted actions via the web interface (sending mail, deleting data etc.). The vulnerability may be used to hide and store malicious content that got injected via another vulnerablity or social engineering. Solution: Users should update to the latest patch releases 2.0.0-rev11 or later.
