arguments to dbus_message_iter_append_basic() were incorrect, assertion "_dbus_check_is_valid_utf8 (*string_p)" failed

    • Open Issue created by werrel3 @werrel3

    Using Debian Testing and vlc 3.0.4.

    When playing a couple of mkv files I have, vlc fails with the assertion:

    VLC media player 3.0.4 Vetinari (revision 3.0.4-0-gf615db63) [0000557e6fbff570] main libvlc: Running vlc with the default interface. Use 'cvlc' to use vlc without interface. dbus[11656]: arguments to dbus_message_iter_append_basic() were incorrect, assertion "_dbus_check_is_valid_utf8 (*string_p)" failed in file ../../../dbus/dbus-message.c line 2754. This is normally a bug in some application using the D-Bus library.

      This really is a bug in libdbus that it crashes if a string is not properly encoded UTF-8. The guys that wrote that library do not understand that input validation is supposed to happen on the receiver, not the sender.

      As to why this crashes your VLC, most probably some invalid meta-data encoding in an input media.

      I got an identical error message when playing a certain DVD (other DVDs work).

      But Interestingly the sample from werrel3 doesn't crash my vlc.

      So my issue might be something different.

      (in case it really is, I'll open another ticket)

      The DVD title is "Einsteins große Idee". So this might be an encoding problem with the German ß letter.

      First 75 MB of the DVD.

      (enough to reproduce the bug - used for the tests mentioned below)

      https://www.dropbox.com/s/0igkzvxkx10u8qr/emc2_head.iso.xz?dl=1

      (use xz to extract before opening in VLC)

      Tested operating systems:

      Debian-11 Testing ("Beta")

      openSUSE-LEAP-15.2

      Debian-11 Testing with it's standard VLC:

      $ LANG=C.UTF-8 vlc -vvv emc2_head.iso

      and try to play some SID files loaded from : https://hvsc.c64.org/

      about 1/10'th of the files i tried will crash VLC.

      e.g.: ./C64Music/GAMES/A-F/Deactivators.sid or ./C64Music/GAMES/A-F/Drol.sid, ... from the archive: | 25.06.2022 | HVSC #77 (and all files from ./C64Music/MUSICIANS/A/Abject/)

      the file loads to the vlc playlist without problems, i can open the media information in vlc without problems (Ctrl+I), but when i try to play the file, VLC crashes with the error message above.

        This really is a bug in libdbus that it crashes if a string is not properly encoded UTF-8.

        I just asked about this on the dbus mailing list. Simon McVittie, who maintains that code, is clear that he does not see this as a bug: all strings for D-Bus must be UTF-8, the behaviour if you pass something else is undefined, and crashing with a descriptive error message is the nicer end of undefined behaviour. Application code should either ensure the data is UTF-8 before passing it to D-Bus, or (if you are designing a protocol) use the array-of-bytes type instead.

        He explained this in far more detail than my summary:

        https://lists.freedesktop.org/archives/dbus/2023-March/018264.html

        I'm posting this to let you know that you've got a 'not our bug' stalemate. I'm not trying to say who's right, and I'm not going to relay replies here back to Simon, so please don't argue with me about it. :wink:

        Sorry but this makes zero sense. You validate what you receive, not what you send. This is utterly common sense, and besides, it is absolutely necessary for security reasons anyhow.

        It would be understandable for the DBus server to cut off the connection here. But it is absolutely NOT OK to crash the client application.

        And that's one of many reason why I find libdbus to be utter garbage. There are way better implementations of the DBus protocol (although the protocol internals although suck big time).

      Oh, and for people experiencing it, setting the environment variable DBUS_FATAL_WARNINGS=0 before running VLC might avoid the crash.

      As I already pointed out a long time ago, this needs a sample. We need to find out why there is a non-UTF8 string here, not why libdbus is helplessly aborting.

        Besides the youtube samples provided above, this can be reproduced by mp4a "network streams" that have non-utf8 characters in the metadata.

        I'm on vlc 3.0.16 on Kubuntu 22.04. It looks to me like it is related to system tray "popups" (notifications) that try to show the title when the remote stream moves to commercials or main program. VLC must be passing invalid characters to the OS?

        dbus[748724]: arguments to dbus_message_iter_append_basic() were incorrect, assertion "_dbus_check_is_valid_utf8 (*string_p)" failed in file ../../../dbus/dbus-message.c line 2760. This is normally a bug in some application using the D-Bus library.

        D-Bus not built with -rdynamic so unable to print a backtrace Aborted (core dumped)

        Again, the stack trace would be useless here. We need to know what is incorrectly injecting invalid strings, not where they are consumed by DBus.
