    hplip vulnerability
    A security issue affects these releases of Ubuntu and its derivatives:
    - Ubuntu 15.04
    - Ubuntu 14.04 LTS
    - Ubuntu 12.04 LTS
    HPLIP could be tricked into downloading a different GPG key when
    performing printer plugin installations.
    Software Description:
    - hplip: HP Linux Printing and Imaging System (HPLIP)
    Enrico Zini discovered that HPLIP used a short GPG key ID when downloading
    keys from the keyserver. An attacker could possibly use this to return a
    different key with a duplicate short key id and perform a man-in-the-middle
    attack on printer plugin installations.
    Update instructions:
    The problem can be corrected by updating your system to the following
    package versions:
    Ubuntu 15.04:
      hplip-data                      3.15.2-0ubuntu4.2
    Ubuntu 14.04 LTS:
      hplip-data                      3.14.3-0ubuntu3.4
    Ubuntu 12.04 LTS:
      hplip-data                      3.12.2-1ubuntu3.5
    In general, a standard system update will make all the necessary changes.
