  [ Dustin Kirkland ]
  * debian/ecryptfs-utils.postinst: LP: #936093

  * precise

  [ Wesley Wiedenmeier ]
  * src/utils/mount.ecryptfs.c: LP: #329264
    - remove old hack, that worked around a temporary kernel regression;
      ensure that all mount memory is mlocked

  [ Sebastian Krahmer ]
  * src/pam_ecryptfs/pam_ecryptfs.c: LP: #732614
    - drop group privileges in the same places that user privileges are
      dropped
    - check return status of setresuid() calls and return if they fail
    - drop privileges before checking for the existence of
      ~/.ecryptfs/auto-mount to prevent possible file existence leakage
      by a symlink to a path that typically would not be searchable by
      the user
    - drop privileges before reading salt from the rc file to prevent the
      leakage of root's salt and, more importantly, using the incorrect salt
    - discovered, independently, by Vasiliy Kulikov and Sebastian Krahmer
  * src/pam_ecryptfs/pam_ecryptfs.c: LP: #1020904
    - after dropping privileges, clear the environment before executing the
      private eCryptfs mount helper
    - discovered by Sebastian Krahmer
  * src/utils/mount.ecryptfs_private.c: LP: #1020904
    - do not allow private eCryptfs mount aliases to contain ".." characters
      as a preventative measure against a crafted file path being used as an
      alias
    - force the MS_NOSUID mount flag to protect against user controlled lower
      filesystems, such as an auto mounted USB drive, that may contain a
      setuid-root binary
      + CVE-2012-3409
    - force the MS_NODEV mount flag
    - after dropping privileges, clear the environment before executing umount
    - discovered by Sebastian Krahmer

  [ Tyler Hicks ]
  * src/libecryptfs/key_management.c: LP: #732614
    - zero statically declared buffers to prevent the leakage of stack
      contents in the case of a short file read
    - discovered by Vasiliy Kulikov
  * src/libecryptfs/module_mgr.c, src/pam_ecryptfs/pam_ecryptfs.c:
