May 11, 2022

firefox vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 21.10
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS

Summary:

Firefox could be made to crash or run programs as your login if it
opened a malicious website.

Software Description:
- firefox: Mozilla Open Source web browser

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 permission prompts, obtain sensitive information,
bypass security restrictions, or execute arbitrary code.

Update instructions:

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

Ubuntu 21.10:
  firefox                         100.0+build2-0ubuntu0.21.10.1

Ubuntu 20.04 LTS:
  firefox                         100.0+build2-0ubuntu0.20.04.1

Ubuntu 18.04 LTS:
  firefox                         100.0+build2-0ubuntu0.18.04.1

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