    tcpdump vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 18.04 LTS
    - Ubuntu 16.04 LTS
    
    Summary:
    
    Several security issues were fixed in tcpdump.
    
    Software Description:
    - tcpdump: command-line network traffic analyzer
    
    Details:
    
    Multiple security issues were discovered in tcpdump. A remote attacker
    could use these issues to cause tcpdump to crash, resulting in a denial of
    service, or possibly execute arbitrary code.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 18.04 LTS:
      tcpdump                         4.9.3-0ubuntu0.18.04.1
    
    Ubuntu 16.04 LTS:
      tcpdump                         4.9.3-0ubuntu0.16.04.1
    
    This update uses a new upstream release, which includes additional bug
    fixes. In general, a standard system update will make all the necessary
    changes.
