This update rebases ghostscript for stretch to the upstream version 9.26 which includes additional changes.

For the stable distribution (stretch), these problems have been fixed in version 9.26~dfsg-0+deb9u1.

We recommend that you upgrade your ghostscript packages.

For the detailed security status of ghostscript please refer to its security tracker page at: [link moved to references]");
