high Nessus Plugin ID 109833

Synopsis

The remote Red Hat host is missing one or more security updates for libvirt.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2018:1396 advisory.

- libvirt: Incomplete fix for CVE-2018-5748 triggered by QEMU guest agent (CVE-2018-1064)

- libvirt: Resource exhaustion via qemuMonitorIORead() method (CVE-2018-5748)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
