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)
