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, spoof the

addressbar, or execute arbitrary code. (CVE-2020-12405, CVE-2020-12406,

CVE-2020-12407, CVE-2020-12408, CVE-2020-12409, CVE-2020-12410,

CVE-2020-12411)

It was discovered that NSS showed timing differences when performing DSA

signatures. An attacker could potentially exploit this to obtain private

keys using a timing attack. (CVE-2020-12399)
