The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:5660 advisory.
mysql: C API unspecified vulnerability (CPU Jan 2020) (CVE-2020-2574)
mysql: C API unspecified vulnerability (CPU Apr 2020) (CVE-2020-2752, CVE-2020-2922)
mariadb-connector-c: Improper validation of content in a OK packet received from server (CVE-2020-13249)
mysql: C API unspecified vulnerability (CPU Jan 2021) (CVE-2021-2007)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
