"The remote MiracleLinux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the
AXSA:2012-975:04 advisory.

    Libvirt is a C toolkit to interact with the virtualization capabilities of recent versions of Linux (and
    other OSes). The main package includes the libvirtd server exporting the virtualization support.
    Security issues fixed with this release:
     CVE-2012-4423
    The virNetServerProgramDispatchCall function in libvirt before 0.10.2 allows remote attackers to cause a
    denial of service (NULL pointer dereference and segmentation fault) via an RPC call with (1) an event as
    the RPC number or (2) an RPC number whose value is in a gap in the RPC dispatch table.
     CVE-2012-3445
    The virTypedParameterArrayClear function in libvirt 0.9.13 does not properly handle virDomain* API calls
    with typed parameters, which might allow remote authenticated users to cause a denial of service (libvirtd
    crash) via an RPC command with nparams set to zero, which triggers an out-of-bounds read or a free of an
    invalid pointer.
    Fixed bugs:
     The augeas libvirt was unable to parse the libvirt.conf file if it contained the host_uuid option; this
    has been fixed.
     Fixed the disk hot-plug functions.
     Fixed the rebase operation; cgroups for the backing files are now relabelled and configured so that, when
    a virtual machine with an image chain using block device is started, the block rebase works as expected
    instead of failing on the blockJobAbort() function.
     Previously, when migrating a guest between 2 machines while the tunnelled migration could cause the
    libvirt daemon to lock up unexpectedly; this has been fixed.
     Depending on the locale in used, libvirt could issue incorrect commands to the hypervisor. This has been
    fixed.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
