    dpdk regression
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 19.10
    - Ubuntu 19.04
    - Ubuntu 18.04 LTS
    
    Summary:
    
    USN-4189-1 introduced a regression in DPDK.
    
    Software Description:
    - dpdk: set of libraries for fast packet processing
    
    Details:
    
    USN-4189-1 fixed a vulnerability in DPDK. The new version introduced a
    regression in certain environments. This update fixes the problem.
    
    Original advisory details:
    
     Jason Wang discovered that DPDK incorrectly handled certain messages. An
     attacker in a malicious container could possibly use this issue to cause
     DPDK to leak resources, resulting in a denial of service.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 19.10:
      dpdk                            18.11.5-0ubuntu0.19.10.1
    
    Ubuntu 19.04:
      dpdk                            18.11.5-0ubuntu0.19.04.1
    
    Ubuntu 18.04 LTS:
      dpdk                            17.11.9-0ubuntu18.04.1
    
    This update uses a new upstream release, which includes additional bug
    fixes. In general, a standard system update will make all the necessary
    changes.
