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.

Affected products

libvirt: through 1.1.3; 0.0.1, 0.0.2, 0.0.3, 0.0.4, 0.0.5, 0.0.6 (+101)
