Summary

This host is missing a security update for Mozilla Firefox.

Insight

Insight

Key detection without JavaScript via SVG animation Security researcher Mario Heiderich reported it was possible to use SVG animation accessKey events to detect key strokes even when JavaScript was disabled. Since web pages can normally detect key events through script and most users have scripting enabled this does not present a risk for most users. In contexts where the user knows scripting is disabled (reading mail, for example, or NoScript users) this could allow a malicious web page to fool a user into interacting with a prompt thinking it came from the browser or mail program.
