Comment
: utils/mount.ecryptfs_private.c in ecryptfs-utils before 90 does not properly check mountpoint permissions, which allows local users to effectively replace any directory with a new filesystem, and consequently gain privileges, via a mount system call.

Comment
: Race condition in the ecryptfs_mount function in fs/ecryptfs/main.c in the eCryptfs subsystem in the Linux kernel before 3.1 allows local users to bypass intended file permissions via a mount.ecryptfs_private mount with a mismatched uid.

Comment
: utils/mount.ecryptfs_private.c in ecryptfs-utils before 90 does not properly maintain the mtab file during error conditions, which allows local users to cause a denial of service (table corruption) or bypass intended unmounting restrictions via a umount system call.

Comment
: The encrypted private-directory setup process in utils/ecryptfs-setup-private in ecryptfs-utils before 90 does not properly ensure that the passphrase file is created, which might allow local users to bypass intended access restrictions at a certain time in the new-user creation steps.
