Details

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)
