Summary
This host is installed with Mozilla Firefox ESR and is prone to multiple Vulnerabilities.
Insight
Insight
Multiple flaws are due to: - A use-after-free vulnerability with a '<canvas>' element on a page. This occurs when a resize event is triggered in concert with style changes but the canvas references have been recreated in the meantime, destroying the originally referenced context. This results in an exploitable crash. - A vulnerablity in the way Firefox handles installation of add-ons.
