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-2011:0583 0 normal SHIPPED_LIVE libcacard and spice-client bug and enhancement update 2011-05-19 09:37:34 UTC

Description Alon Levy 2011-01-17 16:24:02 UTC
Description of problem:
The header field sent in jpeg compressed images which specifies upside downness of the image is being inconsistently handled:
 * server sends 4 or 0
 * client ASSERTS it is 1 or 0
Results in client crash.

Upstream fix for the client:
046b9a7 common, canvas_get_jpeg_alpha: let top_down be any value

Patch makes the client handle 0 as 0 and positive as 1

Version-Release number of selected component (if applicable):
0.7.1

How reproducible:
Always

Steps to Reproduce:
1. start guest with jpeg enabled (force it so it doesn't require emulating a wan environment)
2. in windows guest toggling the start menu repeatedly trigers a jpeg image sent
3. watch client crash
  
Actual results:
client aborts with ASSERT

Expected results:
client works
