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 browser
UI, bypass security restrictions, obtain sensitive information across
domains, or execute arbitrary code.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 21.10

• firefox - 96.0+build2-0ubuntu0.21.10.1

Ubuntu 21.04

• firefox - 96.0+build2-0ubuntu0.21.04.1

Ubuntu 20.04

• firefox - 96.0+build2-0ubuntu0.20.04.1

Ubuntu 18.04

• firefox - 96.0+build2-0ubuntu0.18.04.1

After a standard system update you need to restart Firefox to make
all the necessary changes.
