RHBA-2012:0685 - Bug Fix Advisory

Topic

Updated libvirt packages that fix one bug are now available for Red Hat
Enterprise Linux 6 Extended Update Support.

Description

The libvirt library is a C API for managing and interacting with the
virtualization capabilities of Linux and other operating systems.

This update fixes the following bug:

• An application using the libvirt shared library could terminate unexpectedly

with a segmentation fault when the application tried to unload the library using
the dlclose() function. This could happen for example when shutting down the
tog-pegasus utility while the libvirt-cim provider was in use. This update
modifies linking properties of the library so that the library now prevents
itself from being unloaded from memory. Applications using the libvirt shared
library no longer crash in the described scenario. (BZ#816980)

All users of libvirt are advised to upgrade to these updated packages, which fix
this bug. After installing these updated packages, libvirtd must be restarted.
Use the "service libvirtd restart" command for this update to take effect.
