CVE-2013-4153 libvirt: double free of returned JSON array in qemuAgentGetVCPUs()
Last modified: 2013-07-19 15:26:54 EDT
A part of the returned monitor response was freed twice and caused crashes of the daemon when using guest agent cpu count retrieval.
A remote user able to issue commands to libvirt daemon could use this flaw to crash libvirtd or, potentially, escalate their privilages to that of libvirtd process.
This issue was discovered by Petr Krempa of Red Hat.
