USN-5229-1: Firefox vulnerabilities
13 January 2022
Firefox could be made to crash or run programs as your login if it
opened a malicious website.
o Ubuntu 21.10
o Ubuntu 21.04
o Ubuntu 20.04 LTS
o Ubuntu 18.04 LTS
o firefox - Mozilla Open Source web browser
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.
The problem can be corrected by updating your system to the following package
o firefox - 96.0+build2-0ubuntu0.21.10.1
o firefox - 96.0+build2-0ubuntu0.21.04.1
o firefox - 96.0+build2-0ubuntu0.20.04.1
o firefox - 96.0+build2-0ubuntu0.18.04.1
After a standard system update you need to restart Firefox to make
all the necessary changes.
