1) Buffer overflow (CVE-ID: CVE-2013-4239)

The vulnerability allows a remote #AU# to perform service disruption.

The xenDaemonListDefinedDomains function in xen/xend_internal.c in libvirt 1.1.1 allows remote authenticated users to cause a denial of service (memory corruption and crash) via vectors involving the virConnectListDefinedDomains API function.


2) Resource management error (CVE-ID: CVE-2013-4292)

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

libvirt 1.1.0 and 1.1.1 allows local users to cause a denial of service (memory consumption) via a large number of domain migrate parameters in certain RPC calls in (1) daemon/remote.c and (2) remote/remote_driver.c.


3) Buffer overflow (CVE-ID: CVE-2013-4297)

The vulnerability allows a remote #AU# to perform service disruption.

The virFileNBDDeviceAssociate function in util/virfile.c in libvirt 1.1.2 and earlier allows remote authenticated users to cause a denial of service (uninitialized pointer dereference and crash) via unspecified vectors.
