    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 18.04 LTS
    
    Summary:
    
    Yubico PIV Tool could be made to crash or run programs as an administrator if it
    received specially crafted input.
    
    Software Description:
    - yubico-piv-tool: Command line tool for the YubiKey PIV applet
    
    Details:
    
    It was discovered that libykpiv, a supporting library of the Yubico PIV
    Tool and YubiKey PIV Manager, mishandled specially crafted input. An
    attacker with a custom-made, malicious USB device could potentially execute
    arbitrary code on a computer running the Yubico PIV Tool or Yubikey PIV
    Manager.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 18.04 LTS:
      libykpiv1                       1.4.2-2ubuntu0.1
      ykcs11                          1.4.2-2ubuntu0.1
      yubico-piv-tool                 1.4.2-2ubuntu0.1
