Ubuntu 12.04 LTS / 14.04 LTS / 15.10 / 16.04 LTS : thunderbird vulnerabilities (USN-2973-1)

Critical Nessus Plugin ID 91258

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

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)

Hanno Bock discovered that calculations with mp_div and mp_exptmod in 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.
(CVE-2016-1978)

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).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
