Original advisory details:

 It was discovered that a specially crafted S/MIME message with an inner
 encryption layer could be displayed as having a valid signature in some
 circumstances, even if the signer had no access to the encrypted message.
 An attacker could potentially exploit this to spoof the message author.
 (CVE-2019-11755)

 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 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, CVE-2019-11760,
 CVE-2019-11761, CVE-2019-11762, CVE-2019-11763, CVE-2019-11764)

 A heap overflow was discovered in the expat library in Thunderbird. If a
 user were tricked in to opening a specially crafted message, an attacker
 could potentially exploit this to cause a denial of service, or execute
 arbitrary code. (CVE-2019-15903)");
