Description

This security bulletin contains information about 3 secuirty vulnerabilities.


1) Input validation error (CVE-ID: CVE-2013-2230)

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

The qemu driver (qemu/qemu_driver.c) in libvirt before 1.1.1 allows remote authenticated users to cause a denial of service (daemon crash) via unspecified vectors involving "multiple events registration."


2) Input validation error (CVE-ID: CVE-2013-4154)

The vulnerability allows remote attackers to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can cause a denial of service (NULL pointer dereference and crash) via vectors related to "agent based cpu (un)plug," as demonstrated by the "virsh vcpucount foobar --guest" command.


3) Resource management error (CVE-ID: CVE-2013-2218)

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

Double free vulnerability in the virConnectListAllInterfaces method in interface/interface_backend_netcf.c in libvirt 1.0.6 allows remote attackers to cause a denial of service (libvirtd crash) via a filtering flag that causes an interface to be skipped, as demonstrated by the "virsh iface-list --inactive" command.
