A recent PostgreSQL security flaw may allow unauthorized access to confidential information through the network. It's essential to keep updated on this vital security notice.
PostgreSQL could be made to expose sensitive information over the network.

Summary

PostgreSQL could be made to expose sensitive information over the network.

Software Description:

- postgresql-14: Object-relational SQL database

- postgresql-12: Object-relational SQL database

Kerberos authentication. If a user or automated system were tricked into
