Ubuntu Security Notice 4421-1 - 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, or execute arbitrary code. It was discovered that Thunderbird would continue an unencrypted connection when configured to use STARTTLS for IMAP if the server responded with PREAUTH. A remote attacker could potentially exploit this to perform a person-in-the-middle attack in order to obtain sensitive information. Various other issues were also addressed.
