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-2015:0297 0 normal SHIPPED_LIVE spice-gtk bug fix and enhancement update 2015-03-05 17:33:27 UTC

Description Daniel Berrangé 2013-09-13 12:45:39 UTC
spice-gtk copied the gtk-vnc coroutine_ucontext.c so suffers from this same flaw

+++ This bug was initially created as a clone of Bug #1007837 +++

Description of problem:
The ucontext coroutine implementation mmap()s 16 MB of memory for the coroutine stack, but fails to ever unmap it. This causes the stack to leak for each coroutine started

Version-Release number of selected component (if applicable):
gtk-vnc-0.5.2-2.el7

How reproducible:
Always


Steps to Reproduce:
1. Run demo program in https://bugzilla.gnome.org/show_bug.cgi?id=705827 it will consume memory until exhausted, then crash.
2.
3.
