RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Red Hat Product Errata RHBA-2016:2261 0 normal SHIPPED_LIVE freerdp bug fix update 2016-11-03 13:32:50 UTC

Description Helio Chissini de Castro 2015-04-08 18:58:08 UTC 
Sound event coming from Windows remote desktop causes a crash on pulseaudio queue.
Backtrace analysis show that an invalid packet from a sound notification caused the issue

Customer reported that what caused the issue in two of the crashes was outlook new mail notification.

The current command line is:
xfreerdp --plugin cliprdr --plugin rdpsnd -g 1680x1050 -D -u xxxxx -a 16 -x 0x80 -d 1upmc-acct xxxxxxx

Frame 5 is the crash happened.
Comment 2 Ondrej Holy 2015-04-21 09:55:05 UTC 
It isn't caused only by Outlook according the Bug 1054987 for Fedora.
Comment 3 Ondrej Holy 2015-04-21 09:55:43 UTC 
I've tried to reproduce the crashes, however unsuccessfully. Is it possible to reproduce the crash by playing e.g. "New Mail Notification" from "Sound" dialog in "Control panel"?
Comment 4 Ondrej Holy 2015-04-28 08:46:58 UTC 
Alsa backend can be used as a workaround "--plugin rdpsnd --data alsa --".
Comment 7 Ondrej Holy 2015-06-11 13:04:17 UTC 
Finally I'm able to reproduce the crashes on Fedora rawhide with freerdp mock-build from Fedora 20. It seems the crashes occur only in x86_64. I'm not able to reproduce them in VM and valgrind.

I connect to Microsoft Windows Server 2008 using the following command line:
xfreerdp -u USER -p PASSWORD --plugin rdpsnd SERVER

Then I play the following radio stream using Windows Media Player:
https://api.play.cz/radio/croddur192.asx

Consequently xfreerdp crashes usually in less then 2 minutes with one of the following asserts:
Assertion 'e->mainloop->n_enabled_defer_events > 0' failed at pulse/mainloop.c:257, function mainloop_defer_enable(). Aborting.
Assertion '!e->next' failed at pulsecore/queue.c:104, function pa_queue_pop(). Aborting.
Assertion 'q->front' failed at pulsecore/queue.c:81, function pa_queue_push(). Aborting.
Comment 8 Ondrej Holy 2015-06-11 13:06:41 UTC 
The crashes are caused because pa_stream_trigger() isn't called under the lock. I've already proposed fix upstream, see:
https://github.com/FreeRDP/FreeRDP/pull/2694

Big thanks for Wim Taymans who helped me a lot with addressing the issue.
