[ubuntu/xenial-security] ubuntu-core-launcher 1.0.27.1 (Accepted)

ubuntu-core-launcher (1.0.27.1) xenial-security; urgency=medium

  * SECURITY UPDATE: delayed attack snap data theft and privilege escalation
    when using Snappy on traditional Ubuntu (classic) systems (LP: #1576699)
    - src/main.c: remove glob code and hardcode /snap/ubuntu-core/current
      instead. The glob code both used an improper glob and performed an
      incorrect check due to a typo which allowed a snap named ubuntu-core-...
      to be bind mounted into application runtimes instead of the ubuntu-core
      OS snap. Ubuntu Core removed .<origin> and .sideload from the SNAP path
      so the glob can simply be dropped.
    - CVE-2016-1580
  * debian/usr.bin.ubuntu-core-launcher:
    - only allow mounting /snap/ubuntu-core/*/... to safeguard against this in
      the future
    - add lib32 and libx32 to match setup_snappy_os_mounts()
