This bug was fixed in the package cups-filters - 1.27.2-1
---------------
cups-filters (1.27.2-1) unstable; urgency=medium
* New 1.27.2 upstream release
- cups-browsed: Additional checks against crashes in the
is_local_hostname() function (LP: #1863716)
- foomatic-rip: Zero-page-job handling changes made the last
page of PostScript files not printed, also turning one-page
jobs into zero-page jobs; so drop upstream backport patch.
