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

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. (CVE-2016-6794)

* 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)
