Details
Multiple security issues were discovered in Firefox. If a user were
tricked into opening a specially crafted website, an attacker could
potentially exploit these to cause a denial of service, spoof the mouse
pointer position, bypass Subresource Integrity protections, obtain
sensitive information, or execute arbitrary code.
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 20.04
Ubuntu 18.04
After a standard system update you need to restart Firefox to make
all the necessary changes.
