    Alexander Lakhin discovered that the autovacuum feature and multiple commands could escape the security-
    restricted operation sandbox. For additional information please refer to the upstream announcement at
    https://www.postgresql.org/support/security/CVE-2022-1552// For the oldstable distribution (buster), this
    problem has been fixed in version 11.16-0+deb10u1. We recommend that you upgrade your postgresql-11
    packages. For the detailed security status of postgresql-11 please refer to its security tracker page at:
    https://security-tracker.debian.org/tracker/postgresql-11

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
