"Berkeley Roshan Churchill reported a regression for the recent
security update for ghostscript, announced as DLA-1527-1, caused by an
incomplete fix for CVE-2018-16543. The pdf2ps tool failed to produce
any output and aborted with /rangecheck in .installpagedevice error.

For Debian 8 'Jessie', this problem has been fixed in version
9.06~dfsg-2+deb8u10.

We recommend that you upgrade your ghostscript packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
