Ubuntu Security Notice 2973-1 - 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. Hanno Boeck discovered that calculations with mp_div and mp_exptmod in NSS produce incorrect results in some circumstances, resulting in cryptographic weaknesses. Various other issues were also addressed.

Red Hat Security Advisory 2016-0684-01 - Network Security Services is a set of libraries designed to support the cross-platform development of security-enabled client and server applications. Netscape Portable Runtime provides platform independence for non-GUI operating system facilities. The following packages have been upgraded to a newer upstream version: nss 3.21.0, nspr 4.11.0. Security Fix: A use-after-free flaw was found in the way NSS handled DHE and ECDHE handshake messages. A remote attacker could send a specially crafted handshake message that, when parsed by an application linked against NSS, would cause that application to crash or, under certain special conditions, execute arbitrary code using the permissions of the user running the application.

Red Hat Security Advisory 2016-0685-01 - Network Security Services is a set of libraries designed to support the cross-platform development of security-enabled client and server applications. A use-after-free flaw was found in the way NSS handled DHE (Diffie-Hellman key exchange) and ECDHE (Elliptic Curve Diffie-Hellman key exchange) handshake messages. A use-after-free flaw was found in the way NSS processed certain DER (Distinguished Encoding Rules) encoded cryptographic keys.
