"The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are
affected by a vulnerability as referenced in the SUSE-SU-2024:1652-1 advisory.

  - Missing authorization in PostgreSQL built-in views pg_stats_ext and pg_stats_ext_exprs allows an
    unprivileged database user to read most common values and other statistics from CREATE STATISTICS commands
    of other users. The most common values may reveal column values the eavesdropper could not otherwise read
    or results of functions they cannot execute. Installing an unaffected version only fixes fresh PostgreSQL
    installations, namely those that are created with the initdb utility after installing that version.
    Current PostgreSQL installations will remain vulnerable until they follow the instructions in the release
    notes. Within major versions 14-16, minor versions before PostgreSQL 16.3, 15.7, and 14.12 are affected.
    Versions before PostgreSQL 14 are unaffected. (CVE-2024-4317)

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