[Bug 1885313] Re: evince crashes when opening rfc8798.pdf
The tested snaps indeed use the same libpoppler version as found in 18.04. I have created a 20.04 boot medium and tested evince using the "try Ubuntu without installation". This did indeed work, so I stand corrected that the bug is fixed in current Ubuntu releases. The evince version in 20.04 is 3.36.0 (older than the latest/candidate snap), libpoppler and poppler-utils are version 0.86.1 (newer than in the snaps, or in Debian). So this does look like a poppler rather than evince problem.

[Bug 1885313] Re: evince crashes when opening rfc8798.pdf
The Debian bug report clearly shows that current unstable still exhibits the bug. Since Ubuntu is based on unstable, every Ubuntu version, released or in development, still exhibits this bug. As before, the bug is closed as "fixed", but it is not fixed. The first possible fix in an LTS release is in 22.04 LTS, if upstream picks the problem up and really fixes it. But since this report seems to show that it already is fixed, they might be lured into thinking it is fixed already. It is not. Even if we assume that the bug was fixed in 19.10 and then re-appeared, and possibly fixed in some experimental code base, just closing this bug is the surest way to have it re-appear again, because it was never diagnosed and knowingly fixed, but rather happened to not show itself in some random version of the software. This is very frustrating, and one of the reasons many people still think commercial proprietary software is of better quality than free software (as evidenced, e.g., in the IETF mailing list thread[1]). :-( [1] https://mailarchive.ietf.org/arch/msg/tools- discuss/vIR4w4Qgj796wcTkiNtK6ljMxss/ The poppler-using xpdf in 18.04 does not have this issue. The tools from poppler-utils work fine with the PDF documents in question. So is it really an issue in poppler? Or rather in the way evince uses poppler? I am not familiar with either code base, so I have no idea. The GNOME Document Viewer "evince" stands out as the only PDF viewer that actually crashes on those PDFs. Others display the PDFs, with some (e.g., MuPDF and gv) producing warning and/or error messages (but still correctly displaying the document). It also stands out as the default PDF viewer in Ubuntu. It is not a problem of PDF attachments not working in poppler based PDF viewers, because (using, e.g., pdftk) it is possible to take the problematic PDFs, extract the attachment, create a new PDF without attachment, but otherwise the same contents, and then (re-)attach the file extracted in the first step. The result works fine in evince (and does not produce error nor warning messages in MuPDF). I am sorry for venting my frustration. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to poppler in Ubuntu. https://bugs.launchpad.net/bugs/1885313 Title: evince crashes when opening rfc8798.pdf To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/poppler/+bug/1885313/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
[Bug 1885313] Re: evince crashes when opening rfc8798.pdf
Trying different free software PDF readers, at least some of which use
the same PDF library as evince, does not produce any crashes, but error
(or warning) messages for some:
- xpdf works without messages.
- okular works without messages (and can extract the embedded XML).
- Firefox works without messages (and can extract the embedded XML).
- Chrome works without messages.
- pdfdetach (from poppler-utils) can extract the embedded XML file.
- pdftk can extract the XML.
- mupdf works with error and warning messages:
error: Unable to read ICC workflow
warning: Attempt to read Output Intent failed
- gv works with error messages:
Error: ignoring annotation with scale factor of 0
Output may be incorrect.
Error: Ignoring invalid annotation, output may be incorrect.
Error: ignoring annotation with scale factor of 0
Output may be incorrect.
Error: Ignoring invalid annotation, output may be incorrect.
The PDF document can be transformed to be acceptable to evince: recreating the
PDF with pdftk results in a file that works without errors, even in evince.
But 'mutool clean' does not change anything.
This issue seems to be specific to evince, and affect many versions,
including recent ones.

[Bug 1885313] Re: evince crashes when opening rfc8798.pdf
To test newer versions of evince I have installed evince via the snap store. After installation via snap, the snap version can be started using its different program icon (I hope you can understand what I mean, I clicked the "9 dots" icon in the bottom of the task bar on the left, typed "evince", found two versions using different icons, and verified the version via "Show Details"). * 3.34.2+git4.91cbe4fe (from 2020-06-01) crashes with all the RFC PDF documents of this bug and bug #1849888 (which does cast some doubt about that bug being fixed in evince version 3.34.1-1). * 3.36.6+git2.ce03847a (from 2020-06-27) crashes as well. * 3.37.2+git65.582b220e (from 2020-06-30) does not start, so result for the problematic RFC PDFs. So at least _this_ bug is relevant to more recent versions of evince than the 18.04 LTS default.

[Bug 1885313] Re: evince crashes when opening rfc8798.pdf
The problem may be related to how exactly an XML file is embedded inside the RFC PDF documents. See https://mailarchive.ietf.org/arch/msg/tools-discuss/12Efvwr7KXrgjVTWpaR4pa2hv-U . Removing the embedded file with 'pdftk rfc8798.pdf cat output rfc8798-no_xml.pdf' results in a PDF that evince can display. Re-adding the embedded XML file with 'pdftk rfc8798-no_xml.pdf attach_file rfc8798.xml output rfc8798-pdftk-embed.pdf' again results in a PDF that works fine with evince. Thus it is not the fact that an XML file is embedded that results in the evince crash, but rather the exact procedure used respective the specific result of document processing as done when creating a PDF rendering of an RFC for publication. This still is a bug in evince, because evince is not supposed to perform invalid memory accesses and crash. Especially since other PDF viewers (e.g., Firefox) can display the PDF without visible problems (MuPDF creates error and warning messages, but still displays the PDF correctly). -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to evince in Ubuntu. https://bugs.launchpad.net/bugs/1885313 Title: evince crashes when opening rfc8798.pdf To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/evince/+bug/1885313/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

While this crash looks similar, and all the other problematic RFC documents still crash the evince version in 18.04, there is another report of issues with this specific file on an IETF mailing list: https://mailarchive.ietf.org/arch/msg/tools-discuss/hgenvnKeP9zX- IBX5FyD6zyEkmI There it is reported that evince versions 3.30.2 and 3.36.5 cannot open _this_ file (https://www.rfc-editor.org/rfc/rfc8798.pdf). Since the evince in 19.10 that supposedly fixes the issue in bug #1849888 is 3.34.1-1, this bug is with a high probability _not_ a duplicate of said bug. It probably is related, but not the same. And while initially all new format RFCs crashed evince, in the interim many additional new format RFCs have been published, and not all of them crash evince, not even the version in 18.04. Looking at the evince versions in 20.04 (3.36.0-2) and the in- development "groovy" (3.36.5-2), this issue may well affect all the bleeding edge Ubuntu versions as well, opposed to #1849888. Thus I do think that this bug is distinct from #1849888 and not a duplicate.

[Bug 1849888] Re: evince crashes (segmentation fault) when opening file rfc8655.pdf
To add a bit of background: the IETF (standards body for the Internet) decided to change the format of their newly published standards from ASCII text to XML. From this XML both HTML and PDF versions are generated (and a text version which may omit diagrams / pictures). The PDF version cannot be read on Ubuntu 18.04 with default configuration, because the default document viewer evince crashes when opening the file. ** Summary changed: - evince crashes (segmentation fault) when opening file rfc8655.pdf + evince crashes (segmentation fault) when opening file rfc8655.pdf and other new-format Internet standards -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to evince in Ubuntu. https://bugs.launchpad.net/bugs/1849888 Title: evince crashes (segmentation fault) when opening file rfc8655.pdf and other new-format Internet standards To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/evince/+bug/1849888/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

[Bug 1849888] [NEW] evince crashes (segmentation fault) when opening file rfc8655.pdf
Public bug reported: When trying to display the PDF file rfc8655.pdf from https://tools.ietf.org/pdf/rfc8655.pdf evince crashes: $ evince rfc8655.pdf Segmentation fault (core dumped) I would have expected the PDF file to be displayed. 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). ** Affects: evince (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to evince in Ubuntu. https://bugs.launchpad.net/bugs/1849888 Title: evince crashes (segmentation fault) when opening file rfc8655.pdf To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/evince/+bug/1849888/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
[Bug 1590674] [NEW] ExtremeXOS pager does not work correctly in gnome-terminal, because gnome-terminal ignores the CSI CUB control sequence used by ExtremeXOS
Public bug reported: The pager of the ExtremeXOS switch operating system's CLI uses the (not strictly correct) control sequence "CSI60;D" to delete the pager prompt before displaying the next line of output. The correct control sequence would be "CSI60D" (without a semicolon), but basically all other terminal emulators accept both forms (tested with screen, xterm, rxvt, PuTTY (on Windows), Mac OS X terminal). This affects working with Extreme Networks switches using the default terminal application in Ubuntu. Windows (PuTTY) and Mac OS X (terminal application) users do not experience a similar problem. A simple test to check the control sequence is: printf 'CSI CUB with semicolon is not\x1b[4;D accepted\n' In gnome-terminal this prints: "CSI CUB with semicolon is not[4;D accepted" In screen, xterm, and rxvt this prints: "CSI CUB with semicolon is accepted" Changing the above command to not contain a semicolon works on gnome- terminal as well: printf 'CSI CUB without semicolon is not\x1b[4D accepted\n' In gnome-terminal, screen, xterm, and rxvt this prints "CSI CUB without semicolon is accepted" Thus gnome-terminal breaks backwards-compatibility by a too-pedantic interpretation of VT100 control sequences. As a result it is less convenient to use Ubuntu when working with products of Extreme Networks than using Windows or Mac OS X. If some one wants to verify this with ExtremeXOS, the EXOS VM available on GitHub (https://github.com/extremenetworks/Virtual_EXOS) can be used.
