=====================================================================

1. Summary:

Updated OpenShift Container Storage packages fixing various security issues
and other bugs are now available for Red Hat OpenShift Container Storage
with 3.11.z Async update.

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:

Red Hat Gluster Storage Server 3.5 on RHEL-7 – x86_64
Red Hat Storage Native Client for Red Hat Enterprise Linux 7 – x86_64

3. Description:

Red Hat OpenShift Container Storage(OCS) is a provider of agnostic
persistent storage for OpenShift Container Platform either in-house or in a
hybrid cloud. As a Red Hat storage solution, OCS is completely integrated
with OpenShift Container Platform for deployment, management, and
monitoring.

Security Fix(es):

* gluster-block: information disclosure through world-readable
gluster-block log files (CVE-2020-10762)

* heketi: gluster-block volume password details available in logs
(CVE-2020-10763)

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):

* Earlier, the tcmu-runner did not give details about the file operations
stuck at the backend glusterfs block hosting volume. With this change, the
tcmu-runner is now able to log details about the file operations stuck at
the backend glusterfs block hosting volume and this will help identify the
root cause of the input/output errors easily. (BZ#1850361)

* Earlier, there was no log rotation with gluster-block logs. With this
release, log rotation is possible for gluster-block and tcmu-runner
relevant logs. (BZ#1850365)

* Earlier, heketi did not track all the changes made to volumes as part of
device remove operation. With this release, heketi’s device remove
operation is fully tracked and is based on a series of brick evict
operations making the operation more reliable. (BZ#1850072)

* An access flaw CVE-2020-13867 was found in targetcli due to which the
files under ‘/etc/target’ and ‘/etc/target/backup’ directory were widely
accessible. With this release, the access flaw is fixed as a workaround in
gluster-block to protect these files from any potential attacks for
accessing sensitive information, until the flaw is resolved and made
available in targetcli.(BZ#1850077)

All Red Hat OpenShift Container Storage users are advised to upgrade to
these updated packages.
