The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2019:4273 advisory.
HTTP/2: flood using PING frames results in unbounded memory growth (CVE-2019-9512)
HTTP/2: flood using HEADERS frames results in unbounded memory growth (CVE-2019-9514)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
