It was discovered that some privileged Postscript operators remained accessible from various places. For instance a specially crafted PostScript file could use this flaw in order to have access to the file system outside of the constrains imposed by -dSAFER.
This problem exists because of an incomplete fix for CVE-2019-3839.
For Debian 9 stretch, this problem has been fixed in version 9.26a~dfsg-0+deb9u9.
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]
