CVE-2023-2454:

schema_element defeats protective search_path changes; It was found that certain database calls in PostgreSQL could permit an attacker with elevated database-level privileges to execute arbitrary code.

CVE-2023-2455:

Row security policies disregard user ID changes after inlining; PostgreSQL could permit incorrect policies to be applied in certain cases where role-specific policies are used and a given query is planned under one role and then executed under other roles.


For Debian 9 stretch, these problems have been fixed in version 9.6.24-0+deb9u4.

We recommend that you upgrade your postgresql-9.6 packages.
