Gentoo Linux Security Advisory 201701-46 - Multiple vulnerabilities have been found in NSS, the worst of which could allow remote attackers to obtain access to private key information. Versions less than 3.28 are affected.
0f6eee195afeafb86e9cd1a3fcd4d929Gentoo Linux Security Advisory 201512-10 - Multiple vulnerabilities have been found in Mozilla Firefox and Thunderbird, the worst of which may allow user-assisted execution of arbitrary code. Versions less than 38.5.0 are affected.
5a2f23b04bc19cb5b4340595d101640eRed Hat Security Advisory 2015-1664-01 - Network Security Services is a set of libraries designed to support cross-platform development of security-enabled client and server applications. It was found that NSS permitted skipping of the ServerKeyExchange packet during a handshake involving ECDHE. A remote attacker could use this flaw to bypass the forward-secrecy of a TLS/SSL connection. A flaw was found in the way NSS verified certain ECDSA signatures. Under certain conditions, an attacker could use this flaw to conduct signature forgery attacks.
ae3db96a1a12a86e9c9225fc9523dc97Debian Linux Security Advisory 3336-1 - Several vulnerabilities have been discovered in nss, the Mozilla Network Security Service library.
5241ef6147d66d1d82bcf24640a2aad9Debian Linux Security Advisory 3324-1 - Multiple security issues have been found in Icedove, Debian's version use-after-frees and other implementation errors may lead to the execution of arbitrary code or denial of service. This update also addresses a vulnerability in DHE key processing commonly known as the "LogJam" vulnerability.
944f2e0a822d01ab27afce479671e1f4Ubuntu Security Notice 2673-1 - Karthikeyan Bhargavan discovered that NSS incorrectly handled state transitions for the TLS state machine. If a remote attacker were able to perform a man-in-the-middle attack, this flaw could be exploited to skip the ServerKeyExchange message and remove the forward-secrecy property. Bob Clary, Christian Holler, Bobby Holley, and Andrew McCreight discovered multiple memory safety issues 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 via application crash, or execute arbitrary code with the privileges of the user invoking Thunderbird. Various other issues were also addressed.
cf4bb8c52ccde189b678d4ea6090ad4fUbuntu Security Notice 2656-2 - USN-2656-1 fixed vulnerabilities in Firefox for Ubuntu 14.04 LTS and later releases. This update provides the corresponding update for Ubuntu 12.04 LTS. Karthikeyan Bhargavan discovered that NSS incorrectly handled state transitions for the TLS state machine. If a remote attacker were able to perform a man-in-the-middle attack, this flaw could be exploited to skip the ServerKeyExchange message and remove the forward-secrecy property. Looben Yan discovered 2 use-after-free issues when using XMLHttpRequest in some circumstances. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking Firefox. Various other issues were also addressed.

If a remote attacker were able to perform a man-in-the-middle attack, this flaw could be exploited to skip the ServerKeyExchange message and remove the forward-secrecy property. Watson Ladd discovered that NSS incorrectly handled Elliptical Curve Cryptography (ECC) multiplication. A remote attacker could possibly use this issue to spoof ECDSA signatures. Various other issues were also addressed.
