The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2018:1820 advisory.

    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):

    * procps-ng, procps: Integer overflows leading to heap overflow in file2strvec (CVE-2018-1124)

    * procps-ng, procps: incorrect integer size in proc/alloc.* leading to truncation / integer overflow     issues (CVE-2018-1126)

    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 Qualys Research Labs for reporting these issues.

    Bug Fix(es):

    * Previously some SELinux %post scripts were not re-executed because imgbased attempts to re-execute RPM     %post scripts which involve SELinux commands inside a namespace, and some commands failed due to SELinux     namespacing rules.

    This update ensures that SELinux contexts inside imgbased update namespaces now update appropriately, and     the scripts are re-executed by remounting /sys and /sys/fs/selinux inside the update namespace.
    (BZ#1571607)

    * Previously, vmcore files that were created by kdump were not relabelled by kdumpctl after a reboot. As a     result, Rsync returned an error when trying to remove the security.selinux attribute while syncing     unlabelled files, as this is forbidden by selinux.

    In this release, restorecon is run on the source directory before syncing it, which enables the files to     be synchronized with the correct labels. (BZ#1579141)

    Enhancement(s):

    * Previously, imgbased filtered out stderr from LVM commands to improve parsing reliability. In this     release, imgbased now logs stderr from LVM commands in order to provide this information in the imgbased     logs, for example during an upgrade failure. (BZ#1574187)
