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 spoof the addressbar
contents, conduct cross-site scripting (XSS) attacks, cause a denial of
service via application crash, or execute arbitrary code. (CVE-2017-5432,
CVE-2017-5433, CVE-2017-5434, CVE-2017-5435, CVE-2017-5437, CVE-2017-5438,
