data. An attacker could potentially exploit this to obtain sensitive
information. (CVE-2020-6792)

Multiple security issues were discovered in Thunderbird. If a user were
tricked in to opening a specially crafted message, an attacker could
potentially exploit these to cause a denial of service, obtain sensitive
information, or execute arbitrary code. (CVE-2020-6793, CVE-2020-6795,
CVE-2020-6822)

It was discovered that if a user saved passwords before Thunderbird 60
and then later set a master password, an unencrypted copy of these
passwords would still be accessible. A local user could exploit this to
obtain sensitive information. (CVE-2020-6794)

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,
conduct cross-site scripting (XSS) attacks, obtain sensitive information,
or execute arbitrary code. (CVE-2019-20503, CVE-2020-6798, CVE-2020-6800,
CVE-2020-6805, CVE-2020-6806, CVE-2020-6807, CVE-2020-6812, CVE-2020-6814,
CVE-2020-6819, CVE-2020-6820, CVE-2020-6821, CVE-2020-6825)

It was discovered that the Devtools Copy as cURL feature did not
fully escape website-controlled data. If a user were tricked in to using
the Copy as cURL feature to copy and paste a command with specially
crafted data in to a terminal, an attacker could potentially exploit this
to execute arbitrary commands via command injection. (CVE-2020-6811)");
