Red Hat Bugzilla 1640158 0 unspecified CLOSED Chromium segfaults when attempting to handle GSSAPI requests to fedoraproject.org 2021-02-22 00:41:40 UTC

Internal Links: 1640158

Description Miro Hrončok 2017-01-19 17:12:14 UTC
Description of problem:
I use two Kerberos setups:

kinit mhroncok@REDHAT.COM # call it Red Hat
kinit churchyard@FEDORAPROJECT.ORG # call it Fedora

I have randomly seen some crashes. I think that the crashes appear when I've only done kinit for Fedora and I visit a website with Red Hat kerberos or the other way around.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. kinit Fedora, make sure you haven't kinited Red Hat
2. visit https://mojo.redhat.com/docs/DOC-997854

1. kinit Red Hat, make sure you haven't kinited Fedora
2. visit Koji

Actual results:
[1:1:0100/000000:ERROR:broker_posix.cc(41)] Invalid node channel message
Segmentation fault (core dumped [...])

Expected results:
The website should ask for my credentials.

Additional info:
The crash does not happen always. But once it crashes, it crashes again and again when restoring open tabs. There might be other factors such as how old is the ticket etc. involved.

Comment 1 Tom "spot" Callaway 2017-06-14 15:33:41 UTC
I cannot reproduce this with the 59 builds. Please retest and reopen if you can.

Comment 4 Tom "spot" Callaway 2017-06-15 17:51:24 UTC
I don't have Red Hat krb setup, only Fedora. When I kinit fedora, then go to the URL you've posted, I get prompted to go through the standard single-sign-on process. But I can't reproduce a crash.

Comment 5 NSLW 2017-07-13 11:59:13 UTC
KMyMoney compiled from source (https://cgit.kde.org/kmymoney.git/) started segfaulting randomly on startup. I use Fedora 26 x86_64 and it didn't happen on Fedora 25.
It segfaults randomly and randomly I get
[1:1:0100/000000.564904:ERROR:broker_posix.cc(41)] Invalid node channel message
before segfault.

Recently KMyMoney switched to WebEngine from KHtml, so I could revert that switch easily and the result is that it doesn't segfault.

As a result I narrowed it down to Qt5::WebEngineWidgets (from qt5-qtwebengine 5.9.1-1). I assume it is regression because it didn't segfault on WebEngine 5.8 from Fedora 25 last week.

Comment 6 Tom "spot" Callaway 2017-07-13 15:10:18 UTC
I don't exactly know how the qtwebengine stuff maps to Blink, but if you can identify a patch, I can apply it and see if it resolves the issue for Miro. I still cannot reproduce this locally.

Maybe it doesn't map to Blink but I get the same output before segfault and component set here is chromium, which is WebEngine based, so I thought bug might be in WebEngine.
Ignore if irrelevant.

Comment 8 Fedora End Of Life 2017-11-16 18:56:51 UTC
This message is a reminder that Fedora 25 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 25. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '25'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 25 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged  change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

Comment 9 Fedora End Of Life 2017-12-12 10:50:41 UTC
Fedora 25 changed to end-of-life (EOL) status on 2017-12-12. Fedora 25 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this

Thank you for reporting this bug and we are sorry it could not be fixed.
