The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:0872 advisory.
keycloak: user deletion via incorrect permissions check (CVE-2016-8629)
wildfly: ParseState headerValuesCache can be exploited to fill heap with garbage (CVE-2016-9589)
keycloak: timing attack in JWS signature verification (CVE-2017-2585)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
