This script is Copyright (C) 2017 Tenable Network Security, Inc.

Synopsis :

The remote Oracle Linux host is missing one or more security updates.

Description :

From Red Hat Security Advisory 2017:2247 :

An update for tomcat is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security
impact of Low. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link (s) in the References section.

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

The following packages have been upgraded to a later upstream version:
tomcat (7.0.76). (BZ#1414895)

Security Fix(es) :

* The Realm implementations did not process the supplied password if
the supplied user name did not exist. This made a timing attack
possible to determine valid user names. Note that the default
configuration includes the LockOutRealm which makes exploitation of
this vulnerability harder. (CVE-2016-0762)

* It was discovered that a malicious web application could bypass a
configured SecurityManager via a Tomcat utility method that was
accessible to web applications. (CVE-2016-5018)

* It was discovered that when a SecurityManager was configured,
Tomcat's system property replacement feature for configuration files
could be used by a malicious web application to bypass the
SecurityManager and read system properties that should not be visible.

* It was discovered that a malicious web application could bypass a
configured SecurityManager via manipulation of the configuration
parameters for the JSP Servlet. (CVE-2016-6796)

* It was discovered that it was possible for a web application to
access any global JNDI resource whether an explicit ResourceLink had
been configured or not. (CVE-2016-6797)
