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.

Security readout for executives and security teams

This flaw can let a remote user crash libvirt in configurations that use ACLs. The business impact is service disruption to virtualization management, not disclosed data theft or code execution in the supplied sources. Exposure is most relevant where libvirt remote access is enabled and ACLs are used. The provided affected metadata lacks CPEs, but the CVE description identifies libvirt before 1.1.3. Treat as a targeted availability risk for virtualization operations. Prioritize if libvirt manages production workloads remotely or supports shared infrastructure; otherwise handle through normal legacy vulnerability remediation. Mitigation focus: Upgrade libvirt to 1.1.3 or a vendor-supported patched package.; Review the libvirt advisory and relevant OS vendor advisories.; Inventory systems using libvirt remote access with ACLs enabled..
