It was discovered that Apache Tomcat did not limit the length of chunk
sizes when using chunked transfer encoding. A remote attacker could use
this flaw to perform a denial of service attack against Tomcat by streaming
an unlimited quantity of data, leading to excessive consumption of server
resources. (CVE-2014-0075)

It was found that Apache Tomcat did not check for overflowing values when
parsing request content length headers. A remote attacker could use this
flaw to perform an HTTP request smuggling attack on a Tomcat server located
behind a reverse proxy that processed the content length header correctly.
(CVE-2014-0099)

It was found that the org.apache.catalina.servlets.DefaultServlet
implementation in Apache Tomcat allowed the definition of XML External
Entities (XXEs) in provided XSLTs. A malicious application could use this
to circumvent intended security restrictions to disclose sensitive
information. (CVE-2014-0096)

The CVE-2014-0075 issue was discovered by David Jorm of Red Hat Product
Security.

This update also fixes the following bugs:

  * The patch that resolved the CVE-2014-0050 issue contained redundant code.
This update removes the redundant code. (BZ#1094528)

  * The patch that resolved the CVE-2013-4322 issue contained an invalid
check that triggered a java.io.EOFException while reading trailer headers
for chunked requests. This update fixes the check and the aforementioned
exception is no longer triggered in the described scenario. (BZ#1095602)

All Tomcat 6 users are advised to upgrade to these updated packages, which
contain backported patches to correct these issues. Tomcat must be
restarted for this update to take effect.");
