Title:
  oxide should use an app-specific path for shared memory files

Status in Canonical System Image:
  In Progress
Status in Oxide:
  Fix Released
Status in apparmor-easyprof-ubuntu package in Ubuntu:
  Confirmed

Bug description:
  Oxide creates shared memory files as /run/shm/.org.chromium.Chromium.*. This results in an AppArmor rule like the following:
    owner /run/shm/.org.chromium.Chromium.* rwk, 

  But this rule is too lenient because a malicious app could enumerate
  these files and attack shared memory of other applications. Therefore,
  these paths need to be made application specific.
