   An update that solves four vulnerabilities and has one
   errata is now available.

Description:


   This update for tomcat6 fixes the following issues:

   The version was updated from 6.0.41 to 6.0.45.

   Security issues fixed:

   * 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-2015-5345: 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-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)
