    libssh vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 13.10
    - Ubuntu 12.10
    - Ubuntu 12.04 LTS
    
    Summary:
    
    A security issue was fixed in libssh.
    
    Software Description:
    - libssh: A tiny C SSH library
    
    Details:
    
    Aris Adamantiadis discovered that libssh allowed the OpenSSL PRNG state to
    be reused when implementing forking servers. This could allow an attacker
    to possibly obtain information about the state of the PRNG and perform
    cryptographic attacks.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 13.10:
      libssh-4                        0.5.4-1ubuntu0.1
    
    Ubuntu 12.10:
      libssh-4                        0.5.2-1ubuntu0.12.10.3
    
    Ubuntu 12.04 LTS:
      libssh-4                        0.5.2-1ubuntu0.12.04.3
    
    In general, a standard system update will make all the necessary changes.
