CVE-2013-4399
4.3 · MEDIUMOverview
CVE-2013-4399 is a medium-severity vulnerability affecting redhat libvirt. It was published on December 12, 2014 and has a CVSS 2.0 base score of 4.3 (MEDIUM).
This vulnerability has a CVSS 2.0 base score of 4.3, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
The remoteClientFreeFunc function in daemon/remote.c in libvirt before 1.1.3, when ACLs are used, does not set an identity, which causes event handler removal to be denied and remote attackers to cause a denial of service (use-after-free and crash) by registering an event handler and then closing the connection.
Remediation
Check the references section for vendor advisories and patches from redhat. Update libvirt to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
