1. Summary:

 

An update for tomcat is now available for Red Hat Enterprise Linux 7.

 

Red Hat Product Security has rated this update as having a security impact

of Important. A Common Vulnerability Scoring System (CVSS) base score,

3. Description:

 

Apache Tomcat is a servlet container for the Java Servlet and JavaServer

Pages (JSP) technologies.

 

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)

 

Red Hat would like to thank Dawid Golunski (http://legalhackers.com) for

reporting CVE-2016-5425 and Scott Geary (VendHQ) for reporting

CVE-2016-5388. The CVE-2016-6325 issue was discovered by Red Hat Product

Security.
