The remote Ubuntu host is missing a security-related patch.
Christian Holler, Tyson Smith, and Phil Ringalda discovered multiple
memory safety issues in Thunderbird. If a user were tricked in to
opening a specially crafted message, an attacker could potentially
exploit these to cause a denial of service via application crash, or
execute arbitrary code. (CVE-2016-2805, CVE-2016-2807)

NSS produce incorrect results in some circumstances, resulting in
cryptographic weaknesses. (CVE-2016-1938)
A use-after-free was discovered in ssl3_HandleECDHServerKeyExchange in
NSS. A remote attacker could potentially exploit this to cause a
denial of service via application crash, or execute arbitrary code.
A use-after-free was discovered in
PK11_ImportDERPrivateKeyInfoAndReturnKey in NSS. A remote attacker
could potentially exploit this to cause a denial of service via
application crash, or execute arbitrary code. (CVE-2016-1979).
