Mandriva Linux Security Advisory 2014-195 - An out-of-bounds read flaw was found in the way libvirt's qemuDomainGetBlockIoTune() function looked up the disk index in a non-persistent 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. 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. The updated libvirt packages have been upgraded to the 1.1.3.6 version and patched to resolve these security flaws.

Mandriva Linux Security Advisory MDVSA-2014:195
https://www.mandriva.com/en/support/security/
_______________________________________________________________________
Package : libvirt
Date : October 3, 2014
Affected: Business Server 1.0
_______________________________________________________________________
Problem 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.
