[Test Case] * Install cups-filters version without fix for LP#1828401: 1.20.2-0ubuntu3 in Bionic, and 1.8.3-2ubuntu3.4 in Xenial. * Update ghostscript to/later than fix for CVE-2019-3839-1/-2 9.26~dfsg+0-0ubuntu0.18.04.9 in Bionic / .16.04.9 in Xenial. * Notice it does _not_ update cups-filters to version with fix: 1.20.2-0ubuntu3.1 in Bionic, and 1.8.3-2ubuntu3.5 in Xenial. * $ wget -O ppd-with-pdf-support.ppd \ 'http://www.openprinting.org/ppd-o-matic.php?driver=hl7x0&printer=Brother-HL-1020&show=1' * $ wget -O dummy.pdf \ https://www.w3.org/WAI/ER/tests/xhtml/testfiles/resources/pdf/dummy.pdf * $ foomatic-rip -v --ppd ppd-with-pdf-support.ppd dummy.pdf ... Filetype: PDF GPL Ghostscript 9.26: Unrecoverable error, exit code 1 Process is dying with "Unable to determine number of pages, page count: -1 ", exit stat 3 ... * Note it's broken. * Install ghostscript (test) packages with the relationships 'Breaks: cups-filters (<< 1.20.2-0ubuntu3.1)' in Bionic or 'Breaks: ..., cups-filters (<< 1.8.3-2ubuntu3.5)' in Xenial. * Note it _does_ update cups-filters to version with fix. * $ foomatic-rip -v --ppd ppd-with-pdf-support.ppd dummy.pdf ... Filetype: PDF File contains 1 pages Starting renderer with command: <...> ... * Note it's now working. [Regression Potential] * Low. This only causes an update to cups-filters to a version that fixes an already identified/resolved problem (LP#1828401), which is available in bionic- & xenial-updates since May 2019.
