The remote Redhat Enterprise Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:2493 advisory.

    OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL) and Transport Layer Security (TLS)     protocols, as well as a full-strength general-purpose cryptography library.

    Apache Tomcat is a servlet container for the Java Servlet and JavaServer Pages (JSP) technologies.

    This release provides an update to OpenSSL and Tomcat 6/7 for Red Hat JBoss Web Server 2.1.2. The updates     are documented in the Release Notes document linked to in the References.

    Users of Red Hat JBoss Web Server 2.1.2 should upgrade to these updated packages, which resolve several     security issues.

    Security Fix(es):

    * A memory leak flaw was found in the way OpenSSL handled TLS status request extension data during session     renegotiation. A remote attacker could cause a TLS server using OpenSSL to consume an excessive amount of     memory and, possibly, exit unexpectedly after exhausting all available memory, if it enabled OCSP stapling     support. (CVE-2016-6304)

    * A vulnerability was discovered in tomcat's handling of pipelined requests when Sendfile was used. If     sendfile processing completed quickly, it was possible for the Processor to be added to the processor     cache twice. This could lead to invalid responses or information disclosure. (CVE-2017-5647)

    * A vulnerability was discovered in the error page mechanism in Tomcat's DefaultServlet implementation. A     crafted HTTP request could cause undesired side effects, possibly including the removal or replacement of     the custom error page. (CVE-2017-5664)

    * A denial of service flaw was found in the way the TLS/SSL protocol defined processing of ALERT packets     during a connection handshake. A remote attacker could use this flaw to make a TLS/SSL server consume an     excessive amount of CPU and fail to accept connections from other clients. (CVE-2016-8610)

    Red Hat would like to thank the OpenSSL project for reporting CVE-2016-6304 and Shi Lei (Gear Team of     Qihoo 360 Inc.) for reporting CVE-2016-8610. Upstream acknowledges Shi Lei (Gear Team of Qihoo 360 Inc.)     as the original reporter of CVE-2016-6304.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
