Debian 10 Buster DLA-3600-1: Critical SQL Injection in PostgreSQL

An extension script is vulnerable if it uses @extowner@, @extschema@,
or @extschema:...@ inside a quoting construct (dollar quoting, ', or
"").

For Debian 10 buster, this problem has been fixed in version
11.21-0+deb10u2.

We recommend that you upgrade your postgresql-11 packages.

For the detailed security status of postgresql-11 please refer to
