CVE-2017-16548 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2017-16548):
  The receive_xattr function in xattrs.c in rsync 3.1.2 and 3.1.3-development
  does not check for a trailing '\0' character in an xattr name, which allows
  remote attackers to cause a denial of service (heap-based buffer over-read
  and application crash) or possibly have unspecified other impact by sending
  crafted data to the daemon.
