    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)
