A man-in-the-middle attack in the addon update mechanism has been fixed.

A use-after-free vulnerability in the SVG Animation was discovered, allowing a remote attacker to cause a denial of service (application crash) or execute arbitrary code, if a user is tricked into opening a specially crafted website.
