    Ubuntu Security Notice USN-2883-1
    January 28, 2016
    
    openssl vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 15.10
    
    Summary:
    
    OpenSSL could be made to expose sensitive information over the network.
    
    Software Description:
    - openssl: Secure Socket Layer (SSL) cryptographic library and tools
    
    Details:
    
    Antonio Sanso discovered that OpenSSL reused the same private DH exponent
    for the life of a server process when configured with a X9.42 style
    parameter file. This could allow a remote attacker to possibly discover the
    server's private DH exponent when being used with non-safe primes.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 15.10:
      libssl1.0.0                     1.0.2d-0ubuntu1.3
    
    After a standard system update you need to reboot your computer to make
    all the necessary changes.
