commit: https://git.buildroot.net/buildroot/commit/?id=194c8e543ef9a87407d4c2d5fc3027e221f65e6e
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2018.02.x

Fixes the following security vulnerabilities:

 - CVE-2018-17961: Artifex Ghostscript 9.25 and earlier allows attackers to
   bypass a sandbox protection mechanism via vectors involving errorhandler
   setup.  NOTE: this issue exists because of an incomplete fix for
   CVE-2018-17183.

- CVE-2018-18284: Artifex Ghostscript 9.25 and earlier allows attackers to
  bypass a sandbox protection mechanism via vectors involving the 1Policy
  operator.

- CVE-2018-19409: An issue was discovered in Artifex Ghostscript before
  9.26.  LockSafetyParams is not checked correctly if another device is
  used.

- CVE-2018-19475: psi/zdevice2.c in Artifex Ghostscript before 9.26 allows
  remote attackers to bypass intended access restrictions because available
  stack space is not checked when the device remains the same.

- CVE-2018-19476: psi/zicc.c in Artifex Ghostscript before 9.26 allows
  remote attackers to bypass intended access restrictions because of a
  setcolorspace type confusion.

- CVE-2018-19477: psi/zfjbig2.c in Artifex Ghostscript before 9.26 allows
  remote attackers to bypass intended access restrictions because of a
  JBIG2Decode type confusion.
