opened a malicious website.

Software Description:
- firefox: Mozilla Open Source web browser

Details:

USN-5321-1 fixed vulnerabilities in Firefox. The update didn't include
arm64 because of a regression. This update provides the corresponding
update for arm64.

This update also removes Yandex and Mail.ru as optional search providers
in the drop-down search menu.

Original advisory 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, or execute
  arbitrary code. (CVE-2022-0843, CVE-2022-26381, CVE-2022-26382,
  CVE-2022-26383, CVE-2022-26384, CVE-2022-26385)
   A TOCTOU bug was discovered when verifying addon signatures during
  install. A local attacker could potentially exploit this to trick a
  user into installing an addon with an invalid signature.
