Title: Thunderbird vulnerabilities
Summary: Several security issues were fixed in Thunderbird.
Multiple security issues were discovered in Thunderbird. If a user were
tricked in to opening a specially crafted website in a browsing context,
an attacker could potentially exploit these to cause a denial of service,
obtain sensitive information, or execute arbtirary code. (CVE-2020-12405,

CVE-2020-12419, CVE-2020-12420)
It was discovered that Thunderbird would continue an unencrypted
connection when configured to use STARTTLS for IMAP if the server
responded with PREAUTH. A remote attacker could potentially exploit
this to perform a person-in-the-middle attack in order to obtain
sensitive information. (CVE-2020-12398)

Title: Firefox vulnerabilities
Summary: Firefox could be made to crash or run programs as your login if it
opened a malicious website.
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)
Instructions: After a standard system update you need to restart Firefox to make
all the necessary changes.
