All users of Red Hat Gluster Storage are advised to upgrade to these updated packages, which provide numerous bug fixes and enhancements.

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2018:3470 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):

    * 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)

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)

Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Multiple security vulnerabilities were discovered in GlusterFS, a clustered file system. Buffer overflows and path traversal issues may lead to information disclosure, denial of service or the execution of arbitrary code.

To resolve the security vulnerabilities the following limitations were made in GlusterFS :

  - open,read,write on special files like char and block are     no longer permitted

  - io-stat xlator can dump stat info only to /run/gluster     directory

For Debian 8 'Jessie', these problems have been fixed in version 3.5.2-2+deb8u4.

We recommend that you upgrade your glusterfs packages.
