Summary: An update for imgbased, 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 Moderate. 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. Security Fix(es): * spice: Missing check in demarshal.py:write_validate_array_item() allows for buffer overflow and denial of service (CVE-2018-10873) * glusterfs: Multiple flaws (CVE-2018-10904, CVE-2018-10907, CVE-2018-10923, CVE-2018-10926, CVE-2018-10927, CVE-2018-10928, CVE-2018-10929, CVE-2018-10930, CVE-2018-10911, CVE-2018-10914, CVE-2018-14652, CVE-2018-14653, CVE-2018-14654, CVE-2018-14659, CVE-2018-14660, CVE-2018-14661, CVE-2018-10913) * samba: Insufficient input validation in libsmbclient (CVE-2018-10858) 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. Red Hat would like to thank Michael Hanselmann (hansmi.ch) for reporting CVE-2018-10904, CVE-2018-10907, CVE-2018-10923, CVE-2018-10926, CVE-2018-10927, CVE-2018-10928, CVE-2018-10929, CVE-2018-10930, CVE-2018-10911, CVE-2018-10914, CVE-2018-14652, CVE-2018-14653, CVE-2018-14654, CVE-2018-14659, CVE-2018-14660, CVE-2018-14661, and CVE-2018-10913. The CVE-2018-10873 issue was discovered by Frediano Ziglio (Red Hat). Bug Fix(es): * When upgrading Red Hat Virtualization Host (RHVH), imgbased fails to run garbage collection on previous layers, so new logical volumes are removed, and the boot entry points to a logical volume that was removed. If the RHVH upgrade finishes successfully, the hypervisor boots successfully, even if garbage collection fails. (BZ#1632058) * During the upgrade process, when lvremove runs garbage collection, it prompts for user confirmation, causing the upgrade process to fail. Now the process uses "lvremove --force" when trying to remove logical volumes and does not fail even if garbage collection fails, and as a result, the upgrade process finishes successfully. (BZ#1632585) 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/2974891 5.
