    Package        : postgresql-11
    Version        : 11.20-0+deb10u1
    CVE ID         : CVE-2023-2454 CVE-2023-2455

    Two security issues were found in PostgreSQL, which may result in
    privilege escalation or incorrect policy enforcement.

    For Debian 10 buster, these problems have been fixed in version
    11.20-0+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

    Further information about Debian LTS security advisories, how to apply
    these updates to your system and frequently asked questions can be

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

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