Mandriva Linux Security Advisory : libvirt (MDVSA-2014:195)

This script is Copyright (C) 2014 Tenable Network Security, Inc.


Synopsis :

The remote Mandriva Linux host is missing one or more security
updates.

Description :

Multiple vulnerabilities has been discovered and corrected in
libvirt :

An out-of-bounds read flaw was found in the way libvirt's
qemuDomainGetBlockIoTune() function looked up the disk index in a
non-persistent (live) disk configuration while a persistent disk
configuration was being indexed. A remote attacker able to establish a
read-only connection to libvirtd could use this flaw to crash libvirtd
or, potentially, leak memory from the libvirtd process
(CVE-2014-3633).

A denial of service flaw was found in the way libvirt's
virConnectListAllDomains() function computed the number of used
domains. A remote attacker able to establish a read-only connection to
libvirtd could use this flaw to make any domain operations within
libvirt unresponsive (CVE-2014-3657).

The updated libvirt packages have been upgraded to the 1.1.3.6 version
and patched to resolve these security flaws.
