CVE-2011-1837 (http://nvd.nist.gov/nvd.cfm?cvename=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-2011-1836 (http://nvd.nist.gov/nvd.cfm?cvename=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.

CVE-2011-1835 (http://nvd.nist.gov/nvd.cfm?cvename=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-2011-1834 (http://nvd.nist.gov/nvd.cfm?cvename=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-2011-1832 (http://nvd.nist.gov/nvd.cfm?cvename=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-2011-1831 (http://nvd.nist.gov/nvd.cfm?cvename=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.
