Description Michael Kaplan 2020-11-04 09:06:40 UTC
An attacker having permission to create non-temporary objects in at least one
schema can execute arbitrary SQL functions under the identity of a superuser.
While promptly updating PostgreSQL is the best remediation for most users, a
user unable to do that can work around the vulnerability by disabling
autovacuum and not manually running ANALYZE, CLUSTER, REINDEX, CREATE INDEX,
VACUUM FULL, REFRESH MATERIALIZED VIEW, or a restore from output of the
pg_dump command.  Performance may degrade quickly under this workaround.
VACUUM, without the FULL option, is safe, and all commands are fine when a
trusted user owns the target object.

Comment 13 Stoyan Nikolov 2020-11-17 08:06:46 UTC
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.
