    net-snmp vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 15.04
    - Ubuntu 14.04 LTS
    - Ubuntu 12.04 LTS
    
    Summary:
    
    Net-SNMP could be made to crash or run programs if it received specially
    crafted network traffic.
    
    Software Description:
    - net-snmp: SNMP (Simple Network Management Protocol) server and applications
    
    Details:
    
    It was discovered that Net-SNMP incorrectly handled certain trap messages
    when the -OQ option was used. A remote attacker could use this issue to
    cause Net-SNMP to crash, resulting in a denial of service. (CVE-2014-3565)
    
    Qinghao Tang discovered that Net-SNMP incorrectly handled SNMP PDU parsing
    failures. A remote attacker could use this issue to cause Net-SNMP to
    crash, resulting in a denial of service, or possibly execute arbitrary
    code. (CVE-2015-5621)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 15.04:
      libsnmp30                       5.7.2~dfsg-8.1ubuntu5.1
    
    Ubuntu 14.04 LTS:
      libsnmp30                       5.7.2~dfsg-8.1ubuntu3.1
    
    Ubuntu 12.04 LTS:
      libsnmp15                       5.4.3~dfsg-2.4ubuntu1.3
    
    In general, a standard system update will make all the necessary changes.
