Base vector

AV:A/AC:L/Au:N/C:N/I:N/A:P

Name of the Vulnerable Software and Affected Versions libvirt versions prior to 1.2.1

Description The issue is related to a race condition in the virNetServerClientStartKeepAlive function. This allows remote attackers to cause a denial of service by closing a connection before a keepalive response is sent, resulting in a crash of libvirtd.

Recommendations For versions prior to 1.2.1, update to version 1.2.1 or later to resolve the issue. As a temporary workaround, consider restricting access to the virNetServerClientStartKeepAlive function to minimize the risk of exploitation.
