CVE-2010-1636 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-1636):
  The btrfs_ioctl_clone function in fs/btrfs/ioctl.c in the btrfs
  functionality in the Linux kernel 2.6.29 through 2.6.32, and possibly
  other versions, does not ensure that a cloned file descriptor has
  been opened for reading, which allows local users to read sensitive
  information from a write-only file descriptor.
