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