    net-snmp vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 12.04 LTS
    - Ubuntu 11.10
    - Ubuntu 11.04
    - Ubuntu 10.04 LTS
    - Ubuntu 8.04 LTS
    
    Summary:
    
    Net-SNMP could be made to crash 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 performed entry lookups in the
    extension table. A remote attacker could send a specially crafted request
    and cause the SNMP server to crash, leading to a denial of service.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 12.04 LTS:
      libsnmp15                       5.4.3~dfsg-2.4ubuntu1.1
    
    Ubuntu 11.10:
      libsnmp15                       5.4.3~dfsg-2.2ubuntu1.1
    
    Ubuntu 11.04:
      libsnmp15                       5.4.3~dfsg-2ubuntu1.1
    
    Ubuntu 10.04 LTS:
      libsnmp15                       5.4.2.1~dfsg0ubuntu1-0ubuntu2.2
    
    Ubuntu 8.04 LTS:
      libsnmp15                       5.4.1~dfsg-4ubuntu4.4
    
    In general, a standard system update will make all the necessary changes.
