    ppp vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 14.10
    - Ubuntu 14.04 LTS
    - Ubuntu 12.04 LTS
    
    Summary:
    
    ppp could be made to crash if it received specially crafted network
    traffic.
    
    Software Description:
    - ppp: Point-to-Point Protocol (PPP)
    
    Details:
    
    It was discovered that ppp incorrectly handled large PIDs. When pppd is
    used with a RADIUS server, a remote attacker could use this issue to cause
    it to crash, resulting in a denial of service.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 14.10:
      ppp                             2.4.5-5.1ubuntu3.2
    
    Ubuntu 14.04 LTS:
      ppp                             2.4.5-5.1ubuntu2.2
    
    Ubuntu 12.04 LTS:
      ppp                             2.4.5-5ubuntu1.2
    
    In general, a standard system update will make all the necessary changes.
