CVE-2013-6458

Status Candidate

Overview

Multiple race conditions in the (1) virDomainBlockStats, (2) virDomainGetBlockInf, (3) qemuDomainBlockJobImpl, and (4) virDomainGetBlockIoTune functions in libvirt before 1.2.1 do not properly verify that the disk is attached, which allows remote read-only attackers to cause a denial of service (libvirtd crash) via the virDomainDetachDeviceFlags command.

Red Hat Security Advisory 2014-0103-01

Red Hat Security Advisory 2014-0103-01 - The libvirt library is a C API for managing and interacting with the virtualization capabilities of Linux and other operating systems. In addition, libvirt provides tools for remote management of virtualized systems. A use-after-free flaw was found in the way several libvirt block APIs handled domain jobs. A remote attacker able to establish a read-only connection to libvirtd could use this flaw to crash libvirtd or, potentially, execute arbitrary code with the privileges of the libvirtd process.
