CVE-2013-4399

Publication date 12 December 2014

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

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.
