Detail
A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 15.04 - Ubuntu 14.10 - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS Summary: Several security issues were fixed in NSS. Software Description: - nss: Network Security Service library Details: 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. (CVE-2015-2721) Watson Ladd discovered that NSS incorrectly handled Elliptical Curve Cryptography (ECC) multiplication. A remote attacker could possibly use this issue to spoof ECDSA signatures. (CVE-2015-2730) As a security improvement, this update modifies NSS behaviour to reject DH key sizes below 768 bits, preventing a possible downgrade attack. This update also refreshes the NSS package to version 3.19.2 which includes the latest CA certificate bundle. Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 15.04: Ubuntu 14.10: Ubuntu 14.04 LTS: Ubuntu 12.04 LTS: This update uses a new upstream release, which includes additional bug fixes. After a standard system update you need to restart any applications that use NSS, such as Evolution and Chromium, to make all the necessary changes. References: Package Information: |
