    autofs vulnerability
    A security issue affects these releases of Ubuntu and its derivatives:
    - Ubuntu 14.10
    autofs could be made to run programs as an administrator if program maps
    were configured.
    Software Description:
    - autofs: kernel-based automounter for Linux
    It was discovered that autofs incorrectly filtered environment variables
    when using program maps. When program maps were configured, a local user
    could use this issue to escalate privileges.
    This update changes the default behaviour by adding a prefix to environment
    variables. Sites using program maps will need to adapt to the new variable
    names, or revert to the previous names by using a new configuration option
    Update instructions:
    The problem can be corrected by updating your system to the following
    package versions:
    Ubuntu 14.10:
      autofs                          5.0.8-1ubuntu1.1
    After a standard system update you need to reboot your computer to make
    all the necessary changes.
