CVE-2018-10925
Description
It was discovered that PostgreSQL failed to properly check authorization on certain statements involved with "INSERT ... ON CONFLICT DO UPDATE". An attacker with "CREATE TABLE" privileges could exploit this to read arbitrary bytes server memory. If the attacker also had certain "INSERT" and limited "UPDATE" privileges to a particular table, they could exploit this to update other columns in the same table.

This issue affects the versions of the postsgresql package as shipped with Red Hat Satellite 5.8. However, this flaw is not known to be exploitable under any supported scenario in Satellite 5.8. A future update may address this issue.
