medium Nessus Plugin ID 122738

Language:

Synopsis

The remote Red Hat host is missing a security update for vdsm.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2019:0458 advisory.

 The VDSM service is required by a Virtualization Manager to manage the Linux hosts. VDSM manages and monitors the host's storage, memory and networks as well as virtual machine creation, other host administration tasks, statistics gathering, and log collection.

 The following packages have been upgraded to a later upstream version: vdsm (4.20.47). (BZ#1677458)

 Security Fix(es):

 * vdsm: privilege escalation to root via systemd_run (CVE-2019-3831)

 For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

 Bug Fix(es):

 * VDSM attempted to collect OpenStack related information, even on hosts that are not connected to OpenStack, and displayed a repeated error message in the system log. In this release, errors originating from OpenStack related information are not recorded in the system log. As a result, the system log is quieter. (BZ#1673765)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

Solution

Update the RHEL vdsm package based on the guidance in RHSA-2019:0458.
