-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ==================================================================== Red Hat Security Advisory Synopsis: Important: redhat-virtualization-host security update Advisory ID: RHSA-2018:1275-01 Product: Red Hat Virtualization Advisory URL: https://access.redhat.com/errata/RHSA-2018:1275 Issue date: 2018-05-02 CVE Names: CVE-2018-1088 ==================================================================== 1. Summary: An update for redhat-release-virtualization-host and redhat-virtualization-host is now available for Red Hat Virtualization 4 for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. 2. Relevant releases/architectures: RHEL 7-based RHEV-H for RHEV 4 (build requirements) - noarch, x86_64 Red Hat Virtualization 4 Hypervisor for RHEL 7 - noarch 3. Description: The redhat-virtualization-host packages provide the Red Hat Virtualization Host. These packages include redhat-release-virtualization-host, ovirt-node, and rhev-hypervisor. Red Hat Virtualization Hosts (RHVH) are installed using a special build of Red Hat Enterprise Linux with only the packages required to host virtual machines. RHVH features a Cockpit user interface for monitoring the host's resources and performing administrative tasks. The ovirt-node-ng packages provide the Red Hat Virtualization Host. These packages include redhat-release-virtualization-host, ovirt-node, and rhev-hypervisor. Red Hat Virtualization Hosts (RHVH) are installed using a special build of Red Hat Enterprise Linux with only the packages required to host virtual machines. RHVH features a Cockpit user interface for monitoring the host's resources and performing administrative tasks. Security Fix(es): * glusterfs: Privilege escalation via gluster_shared_storage when snapshot scheduling is enabled (CVE-2018-1088) * It was found that fix for CVE-2018-1088 introduced new vulnerability in the way 'auth.allow' is implemented in glusterfs server. An unauthenticated gluster client could mount gluster storage volumes. (CVE-2018-1112) For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section. This issue was discovered by John Strunk (Red Hat). 4.
