    quagga vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 16.04 LTS
    - Ubuntu 14.04 LTS
    - Ubuntu 12.04 LTS
    
    Summary:
    
    Several security issues were fixed in Quagga.
    
    Software Description:
    - quagga: BGP/OSPF/RIP routing daemon
    
    Details:
    
    It was discovered that Quagga incorrectly handled dumping data. A remote
    attacker could possibly use a large BGP packet to cause Quagga to crash,
    resulting in a denial of service. (CVE-2016-4049)
    
    It was discovered that the Quagga package incorrectly set permissions on
    the configuration directory. A local user could use this issue to possibly
    obtain sensitive information. (CVE-2016-4036)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 16.04 LTS:
      quagga                          0.99.24.1-2ubuntu1.1
    
    Ubuntu 14.04 LTS:
      quagga                          0.99.22.4-3ubuntu1.2
    
    Ubuntu 12.04 LTS:
      quagga                          0.99.20.1-0ubuntu0.12.04.5
    
    After a standard system update you need to restart Quagga to make all the
    necessary changes.
