Several flaws were found in the processing of malformed web content. A web
page containing malicious content could cause Thunderbird to crash or,
potentially, execute arbitrary code with the privileges of the user running
Thunderbird. (CVE-2016-1952, CVE-2016-1954, CVE-2016-1957, CVE-2016-1960,
CVE-2016-1961, CVE-2016-1974, CVE-2016-1964, CVE-2016-1966)

Multiple security flaws were found in the graphite2 font library shipped
with Thunderbird. A web page containing malicious content could cause
Thunderbird to crash or, potentially, execute arbitrary code with the
privileges of the user running Thunderbird. (CVE-2016-1977, CVE-2016-2790,
CVE-2016-2791, CVE-2016-2792, CVE-2016-2793, CVE-2016-2794, CVE-2016-2795,
