Comment: This advisory references vulnerabilities in products which run on

Package        : ghostscript
Version        : 9.05~dfsg-6.3+deb7u8
CVE ID         : CVE-2018-10194
Debian Bug     : 896069

It was discovered that the set_text_distance function in
base/gdevpdts.c in the pdfwrite component in Ghostscript does not
prevent overflows in text-positioning calculation, which allows remote
attackers to cause a denial of service (application crash) or possibly
have unspecified other impact via a crafted PDF document.

For Debian 7 "Wheezy", these problems have been fixed in version
9.05~dfsg-6.3+deb7u8.

We recommend that you upgrade your ghostscript packages.
