Version : 9.6.20-0+deb9u1
CVE ID : CVE-2020-25694 CVE-2020-25695 CVE-2020-25696

Several vulnerabilities have been found in the PostgreSQL database system.

CVE-2020-25694

Peter Eisentraut found that database reconnections may drop options
from the original connection, such as encryption, which could lead
to information disclosure or a man-in-the-middle attack.

CVE-2020-25695

Etienne Stalmans reported that a user with permissions to create
non-temporary objects in an schema can execute arbitrary SQL
functions as a superuser.

CVE-2020-25696

Nick Cleaton found that the \gset command modified variables that
control the psql behaviour, which could result in a compromised or
malicious server executing arbitrary code in the user session.

For Debian 9 stretch, these problems have been fixed in version
9.6.20-0+deb9u1.

We recommend that you upgrade your postgresql-9.6 packages.
