   An update that fixes 7 vulnerabilities is now available.

Description:


   This update for tomcat fixes the following issues:

   Tomcat 8 was updated from 8.0.23 to 8.0.32, to fix bugs and security
   issues.

   Fixed security issues:

   * CVE-2015-5174: Directory traversal vulnerability in RequestUtil.java in
     Apache Tomcat allowed remote authenticated users to bypass intended
     SecurityManager restrictions and list a parent directory via a /..
     (slash dot dot) in a pathname used by a web application in a
     getResource, getResourceAsStream, or getResourcePaths call, as
     demonstrated by the $CATALINA_BASE/webapps directory.  (bsc#967967)
   * CVE-2015-5346: Session fixation vulnerability in Apache Tomcat when
     different session settings are used for deployments of multiple versions
     of the same web application, might have allowed remote attackers to
      hijack web sessions by leveraging use of a requestedSessionSSL field
      for an unintended request, related to CoyoteAdapter.java and
      Request.java. (bsc#967814)
   * CVE-2015-5345: The Mapper component in Apache Tomcat processes redirects
     before considering security constraints and Filters, which allowed
     remote attackers to determine the existence of a directory via a URL
     that lacks a trailing / (slash) character. (bsc#967965)
   * CVE-2015-5351: The (1) Manager and (2) Host Manager applications in
     Apache Tomcat established sessions and send CSRF tokens for arbitrary
     new requests, which allowed remote attackers to bypass a CSRF protection
     mechanism by using a token. (bsc#967812)
   * CVE-2016-0706: Apache Tomcat did not place
     org.apache.catalina.manager.StatusManagerServlet on the
     org/apache/catalina/core/RestrictedServlets.properties list, which
      allowed remote authenticated users to bypass intended SecurityManager
      restrictions and read arbitrary HTTP requests, and consequently
      discover session ID values, via a crafted web application.  (bsc#967815)
   * CVE-2016-0714: The session-persistence implementation in Apache Tomcat
     mishandled session attributes, which allowed remote authenticated users
     to bypass intended SecurityManager restrictions and execute arbitrary
     code in a privileged context via a web application that places a crafted
     object in a session. (bsc#967964)
   * CVE-2016-0763: The setGlobalContext method in
     org/apache/naming/factory/ResourceLinkFactory.java in Apache Tomcat did
      not consider whether ResourceLinkFactory.setGlobalContext callers are
      authorized, which allowed remote authenticated users to bypass intended
      SecurityManager restrictions and read or write to arbitrary application
      data, or cause a denial of service (application disruption), via a web
      application that sets a crafted global context.  (bsc#967966)
