bypass same-origin protections, or execute arbitrary code.
(CVE-2019-18511, CVE-2019-11691, CVE-2019-11692, CVE-2019-11693,

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, or execute
arbitrary code. (CVE-2019-5798, CVE-2019-7317)

A type confusion bug was discovered with object groups and UnboxedObjects.
If a user were tricked in to opening a specially crafted website in a
browsing context after enabling the UnboxedObjects feature, an attacker
could potentially exploit this to bypass security checks. (CVE-2019-9816)

a specially crafted hyperlink to a bookmark toolbar or sidebar, and
