    ppp vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 18.04 LTS
    - Ubuntu 16.04 LTS
    - Ubuntu 14.04 LTS
    
    Summary:
    
    ppp could be made to crash or bypass authentication if it received
    specially crafted network traffic.
    
    Software Description:
    - ppp: Point-to-Point Protocol (PPP)
    
    Details:
    
    Ivan Gotovchits discovered that ppp incorrectly handled the EAP-TLS
    protocol. A remote attacker could use this issue to cause ppp to crash,
    resulting in a denial of service, or possibly bypass authentication.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 18.04 LTS:
      ppp                             2.4.7-2+2ubuntu1.1
    
    Ubuntu 16.04 LTS:
      ppp                             2.4.7-1+2ubuntu1.16.04.1
    
    Ubuntu 14.04 LTS:
      ppp                             2.4.5-5.1ubuntu2.3
    
    In general, a standard system update will make all the necessary changes.
