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, bypass security restrictions, bypass
same-origin restrictions, conduct cross-site scripting (XSS) attacks, or
execute arbitrary code. (CVE-2019-11757, CVE-2019-11758, CVE-2019-11759,
