  could lead to shared memory segments of other users beeing freed
  (bnc#1052984)

- CVE-2017-12184,CVE-2017-12185,CVE-2017-12186,CVE-2017-12187: Fixed
  unvalidated lengths in multiple extensions (bsc#1063034)
- CVE-2017-12183: Fixed some unvalidated lengths in the XFIXES
  extension. (bsc#1063035)
- CVE-2017-12180,CVE-2017-12181,CVE-2017-12182: Fixed various unvalidated
