    libssh vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 12.10
    - Ubuntu 12.04 LTS
    - Ubuntu 11.10
    - Ubuntu 10.04 LTS
    
    Summary:
    
    libssh could be made to crash if it received specially crafted network
    traffic.
    
    Software Description:
    - libssh: A tiny C SSH library
    
    Details:
    
    Yong Chuan Koh discovered that libssh incorrectly handled certain
    negotiation requests. A remote attacker could use this to cause libssh to
    crash, resulting in a denial of service.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 12.10:
      libssh-4                        0.5.2-1ubuntu0.12.10.2
    
    Ubuntu 12.04 LTS:
      libssh-4                        0.5.2-1ubuntu0.12.04.2
    
    Ubuntu 11.10:
      libssh-4                        0.5.2-1ubuntu0.11.10.2
    
    Ubuntu 10.04 LTS:
      libssh-4                        0.4.2-1ubuntu1.2
    
    In general, a standard system update will make all the necessary changes.
