Multiple security issues were discovered in Firefox. If a user were
tricked in to opening a specially crafted website, an attacker could
potentially exploit these to cause a denial of service, obtain sensitive
information, bypass iframe sandbox restrictions, confuse the user, or
execute arbitrary code. (CVE-2020-6463, CVE-2020-6514, CVE-2020-15652,
CVE-2020-15653, CVE-2020-15654, CVE-2020-15656, CVE-2020-15658,
CVE-2020-15659)
