Description
This security bulletin contains information about 1 security vulnerability.
1) Race condition (CVE-ID: CVE-2013-6458)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
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.
Remediation
Install update from vendor's website.
