Security Fix(es):

* It was discovered that the Tomcat packages installed configuration file
/usr/lib/tmpfiles.d/tomcat.conf writeable to the tomcat group. A member of
the group or a malicious web application deployed on Tomcat could use this
flaw to escalate their privileges. (CVE-2016-5425)

* It was discovered that the Tomcat packages installed certain
configuration files read by the Tomcat initialization script as writeable
to the tomcat group. A member of the group or a malicious web application
deployed on Tomcat could use this flaw to escalate their privileges.
(CVE-2016-6325)

* It was found that the expression language resolver evaluated expressions
within a privileged code section. A malicious web application could use
this flaw to bypass security manager protections. (CVE-2014-7810)

* It was discovered that tomcat used the value of the Proxy header from
HTTP requests to initialize the HTTP_PROXY environment variable for CGI
scripts, which in turn was incorrectly used by certain HTTP client
implementations to configure the proxy for outgoing HTTP requests. A
remote attacker could possibly use this flaw to redirect HTTP requests
performed by a CGI script to an attacker-controlled proxy via a malicious
HTTP request. (CVE-2016-5388)

* A session fixation flaw was found in the way Tomcat recycled the
requestedSessionSSL field. If at least one web application was configured
to use the SSL session ID as the HTTP session ID, an attacker could reuse
a previously used session ID for further requests. (CVE-2015-5346)
