Mandriva Linux Security Advisory : libvirt (MDVSA-2015:070)

low Nessus Plugin ID 82323

Language:

Synopsis

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

Description

Updated libvirt packages fixes security vulnerabilities :

The qemuDomainMigratePerform and qemuDomainMigrateFinish2 functions in qemu/qemu_driver.c in libvirt do not unlock the domain when an ACL check fails, which allow local users to cause a denial of service via unspecified vectors (CVE-2014-8136).

The XML getters for for save images and snapshots objects don't check ACLs for the VIR_DOMAIN_XML_SECURE flag and might possibly dump security sensitive information. A remote attacker able to establish a connection to libvirtd could use this flaw to cause leak certain limited information from the domain xml file (CVE-2015-0236).

The updated packages provides the latest 1.1.3.9 version whish has more robust fixes for MDVSA-2015:023 and MDVSA-2015:035.

Solution

Update the affected packages.
