Title: Thunderbird vulnerabilities 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, bypass same-origin protections, or execute arbitrary code.

If a user were tricked in to opening a specially crafted message, an attacker could potentially exploit these to cause a denial of service, or execute arbitrary code. (CVE-2019-5798, CVE-2019-7317) A type confusion bug was discovered with object groups and UnboxedObjects. If a user were tricked in to opening a specially crafted website in a browsing context after enabling the UnboxedObjects feature, an attacker could potentially exploit this to bypass security checks. (CVE-2019-9816) It was discovered that history data could be exposed via drag and drop of hyperlinks to and from bookmarks.
