Description
A flaw was found in postgresql. If a client application that creates additional database connections only reuses the basic connection parameters while dropping security-relevant parameters, an opportunity for a man-in-the-middle attack, or the ability to observe clear-text transmissions, could exist. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
Statement
In Red Hat Gluster Storage 3, PostgreSQL (embedded in rhevm-dependencies) was shipped as a part of Red Hat Gluster Storage Console that is no longer supported for use with Red Hat Gluster Storage 3.5. Red Hat Gluster Storage Web Administration is now the recommended monitoring tool for Red Hat Storage Gluster clusters. In Red Hat Virtualization the manager appliance uses a vulnerable version of postgresql. Once a fix has been shipped for RHEL 8 the appliance can consume the fix via a regular yum update.
