Package        : ghostscript
Version        : 9.26a~dfsg-0+deb9u9
CVE ID         : CVE-2019-25059

A security vulnerability was found in Ghostscript, the GPL PostScript/PDF
interpreter. 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.
