========================================================================== Ubuntu Security Notice USN-3850-1 January 09, 2019
nss vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 18.10 - Ubuntu 18.04 LTS - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS
Summary:
Several security issues were fixed in NSS.
Software Description: - nss: Network Security Service library
Details:
Keegan Ryan discovered that NSS incorrectly handled ECDSA key generation. A local attacker could possibly use this issue to perform a cache-timing attack and recover private ECDSA keys. (CVE-2018-0495)
It was discovered that NSS incorrectly handled certain v2-compatible ClientHello messages. A remote attacker could possibly use this issue to perform a replay attack. (CVE-2018-12384)
It was discovered that NSS incorrectly handled certain padding oracles. A remote attacker could possibly use this issue to perform a variant of the Bleichenbacher attack. (CVE-2018-12404)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 18.10: libnss3 2:3.36.1-1ubuntu1.1
Ubuntu 18.04 LTS: libnss3 2:3.35-2ubuntu2.1
Ubuntu 16.04 LTS: libnss3 2:3.28.4-0ubuntu0.16.04.4
Ubuntu 14.04 LTS: libnss3 2:3.28.4-0ubuntu0.14.04.4
After a standard system update you need to restart any applications that use NSS, such as Evolution, to make all the necessary changes.
