Synopsis:          Important: libvirt security update
Issue date:        2011-03-29
CVE Names:         CVE-2011-1146

It was found that several libvirt API calls did not honor the read-only
permission for connections. A local attacker able to establish a read-only
connection to libvirtd on a server could use this flaw to execute commands
that should be restricted to read-write connections, possibly leading to a
denial of service or privilege escalation. (CVE-2011-1146)

Note: Previously, using rpmbuild without the '--define "rhel 5"' option to 
build the libvirt source RPM could failed with a "Failed build dependencies" 
error for the device-mapper-devel package, as this -devel sub-package may not 
be available. With this update, the -devel sub-package is no longer checked by 
default as a dependency when building , allowing the libvirt source RPM to 
build as expected.
