The problem seems to lie in the new format for IETF RFCs, i.e., all official PDF files of RFCs released using the new format result in evince crashes:

Instead, evince crashed and did not display the document. The built-in PDF renderer of Firefox 70.0 does display the PDF correctly. Since the segmentation fault hints at a memory management error triggered by external input this may have security implications. I did not investigate this any further. I do not set the "This bug is a security vulnerability" flag because I do not know if it really is (it probably is, but I have no proof) and I do not want this bug report to be private. $ lsb_release -rd Description: Ubuntu 18.04.3 LTS Release: 18.04 $ apt-cache policy evince evince: Installed: 3.28.4-0ubuntu1.2 Candidate: 3.28.4-0ubuntu1.2 Version table: *** 3.28.4-0ubuntu1.2 500 500 http://de.archive.ubuntu.com/ubuntu bionic-updates/main amd64 Packages 500 http://security.ubuntu.com/ubuntu bionic-security/main amd64 Packages 100 /var/lib/dpkg/status 3.28.2-1 500 500 http://de.archive.ubuntu.com/ubuntu bionic/main amd64 Packages $ evince --version GNOME Document Viewer 3.28.4 $ cat /etc/lsb-release DISTRIB_ID=Ubuntu DISTRIB_RELEASE=18.04 DISTRIB_CODENAME=bionic DISTRIB_DESCRIPTION="Ubuntu 18.04.3 LTS" This is a fresh install of Ubuntu 18.04 LTS on x86-64 (the upgrade from 16.04 resulted in a non-booting system).
