mount.ecryptfs_private.c in eCryptfs-utils does not validate mount destination filesystem types, which allows local users to gain privileges by mounting over a nonstandard filesystem, as demonstrated by /proc/$pid.
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
