The remote host is missing updates announced in
The libvirt library is a C API for managing and interacting with the
virtualization capabilities of Linux and other operating systems. In
addition, libvirt provides tools for remotely managing virtualized systems.
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 on Red Hat Enterprise Linux 5 failed with a
Failed build dependencies error for the device-mapper-devel package, as
this -devel sub-package is not available on Red Hat Enterprise Linux 5.
With this update, the -devel sub-package is no longer checked by default as
a dependency when building on Red Hat Enterprise Linux 5, allowing the
libvirt source RPM to build as expected.
All libvirt users are advised to upgrade to these updated packages, which
contain a backported patch to resolve this issue. After installing the
updated packages, libvirtd must be restarted (service libvirtd restart)
for this update to take effect.
Please note that this update is available via
Red Hat Network. To use Red Hat Network, launch the Red
Hat Update Agent with the following command: up2date
