CVE-2011-1831

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.

CVE-2011-1837

The lock-counter implementation in utils/mount.ecryptfs_private.c in ecryptfs-utils before 90 allows local users to overwrite arbitrary files via unspecified vectors.

CVE-2011-1832

utils/mount.ecryptfs_private.c in ecryptfs-utils before 90 does not properly check mountpoint permissions, which allows local users to remove directories via a umount system call.

CVE-2011-1834

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.

CVE-2011-1835

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.

CVE-2011-1836

utils/ecryptfs-recover-private in ecryptfs-utils before 90 does not establish a subdirectory with safe permissions, which might allow local users to bypass intended access restrictions via standard filesystem operations during the recovery process.
