Scientific Linux Security Update : libvirt on SL6.x i386/x86_64

medium Nessus Plugin ID 61002

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

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.

Solution

Update the affected packages.
