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.
 (CVE-2022-26387)");
