Debian DLA-1772-1 : libvirt security update

high Nessus Plugin ID 124417

Synopsis

The remote Debian host is missing a security update.

Description

libvirt-domain.c in libvirt supports virDomainGetTime API calls by guest agents with an RO connection, even though an RW connection was supposed to be required. This could lead to could lead to potentially disclosing unintended information or denial of service by causing libvirt to block.

For Debian 8 'Jessie', this problem has been fixed in version 1.2.9-9+deb8u6.

We recommend that you upgrade your libvirt packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
