installing a malicious language pack, an attacker could exploit this to
gain additional privileges. (CVE-2019-9811)
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,
bypass same origin restrictions, conduct cross-site scripting (XSS)
attacks, spoof origin attributes, or execute arbitrary code.

Thunderbird to crash, resulting in a denial of service, or possibly
obtain sensitive information. (CVE-2019-11719)

keys. An attacker could possibly exploit this issue to cause Thunderbird
to crash, resulting in a denial of service. (CVE-2019-11729)
It was discovered that Thunderbird treats all files in a directory as same
origin. If a user were tricked in to downloading a specially crafted HTML
file, an attacker could potentially exploit this to obtain sensitive
information from local files. (CVE-2019-11730)
