CVE-2010-2071 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-2071):
  The btrfs_xattr_set_acl function in fs/btrfs/acl.c in btrfs in the
  Linux kernel 2.6.34 and earlier does not check file ownership before
  setting an ACL, which allows local users to bypass file permissions
  by setting arbitrary ACLs, as demonstrated using setfacl.
