CVE-2013-4154 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:13.04.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libvirt package and not the libvirt package as distributed by Ubuntu.
The qemuAgentCommand function in libvirt before 1.1.1, when a guest agent is not configured, allows remote attackers to 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.
