    - 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.
