Red Hat Insights patch analysis
Identify and remediate systems affected by this advisory.
Topic
An updated rgmanager package that fixes one bug is now available for Red Hat
Enterprise Linux 5 Extended Update Support.
Description
The rgmanager package contains the Red Hat Resource Group Manager, which
provides the ability to create and manage high-availability server applications
in the event of system downtime.
This update fixes the following bug:
- A rare race condition could occur when rgmanager received a request to start a
new resource group thread while another thread was exiting. This race condition
could cause a Time of Check to Time of Use (TOC/TOU) bug, which under certain
circumstances resulted in an attempt to access previously-freed memory. As a
consequence, rgmanager terminated unexpectedly with a segmentation fault. To
avoid the TOC/TOU problem, rgmanager now checks the status of the resource group
thread before attempting to use the thread. This ensures that the thread is
referred to correctly and Resource Group Manager thus no longer crashes in this
scenario. (BZ#786525)
All users of rgmanager are advised to upgrade to this updated package, which
fixes this bug.
Solution
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
