The remote Redhat Enterprise Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2019:4126 advisory.
httpd: mod_http2: DoS via slow, unneeded request bodies (CVE-2018-17189)
httpd: mod_session_cookie does not respect expiry time (CVE-2018-17199)
httpd: mod_auth_digest: access control bypass due to race condition (CVE-2019-0217)
httpd: URL normalization inconsistency (CVE-2019-0220)
httpd: limited cross-site scripting in mod_proxy error page (CVE-2019-10092)
httpd: null-pointer dereference in mod_remoteip (CVE-2019-10097)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
