Bug#928952: Problems after security update 9.26a~dfsg-0+deb9u3

[Paul van der Vlis <paul@vandervlis.nl>]

Package: ghostscript
Version: 9.26a~dfsg-0+deb9u3


After doing the Ghostscript upgrade from 9.26a~dfsg-0+deb9u2 to
9.26a~dfsg-0+deb9u3 cups did not print anymore at a customer PC.
Downgrading the ghostscript package did help.

My customer is using a Brother HL-L2365DW connected through USB with
"Generic PCL6/PCL XL Printer Foomatic/ljet4d" driver.

My Lexmark x546dtn network printer does work fine using postscript after
the upgrade, but not using PCL6. I get there:
Idle - "Filter failed".

I guess there is something wrong with printing PCL6.

Workarround:

apt install libgs9-common=9.26a~dfsg-0+deb9u2 \
 libgs9=9.26a~dfsg-0+deb9u2 ghostscript=9.26a~dfsg-0+deb9u2
systemctl restart cups
make a file /etc/apt/preferences.d/ghostscript for pinning:
---
Package: libgs9-common
Pin: version 9.26a~dfsg-0+deb9u2
Pin-Priority: 1001

Package: libgs9
Pin: version 9.26a~dfsg-0+deb9u2
Pin-Priority: 1001

Package: ghostscript
Pin: version 9.26a~dfsg-0+deb9u2
Pin-Priority: 1001
---
apt update
