1. Summary:

 

Updated tomcat6 packages that fix three security issues are now available

for Red Hat Enterprise Linux 6.

 

The Red Hat Security Response Team has rated this update as having Moderate

security impact. Common Vulnerability Scoring System (CVSS) base scores,

which give detailed severity ratings, are available for each vulnerability

from the CVE links in the References section.

 

2. Relevant releases/architectures:

 

Red Hat Enterprise Linux Desktop Optional (v. 6) - noarch

Red Hat Enterprise Linux HPC Node Optional (v. 6) - noarch

Red Hat Enterprise Linux Server (v. 6) - noarch

Red Hat Enterprise Linux Server Optional (v. 6) - noarch

Red Hat Enterprise Linux Workstation (v. 6) - noarch

3. Description:

 

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

Pages (JSP) technologies.

 

It was found that when Tomcat processed a series of HTTP requests in which

at least one request contained either multiple content-length headers, or

one content-length header with a chunked transfer-encoding header, Tomcat

would incorrectly handle the request. A remote attacker could use this flaw

to poison a web cache, perform cross-site scripting (XSS) attacks, or

obtain sensitive information from other requests. (CVE-2013-4286)

 

It was discovered that the fix for CVE-2012-3544 did not properly resolve a

denial of service flaw in the way Tomcat processed chunk extensions and

trailing headers in chunked requests. A remote attacker could use this flaw

to send an excessively long request that, when processed by Tomcat, could

consume network bandwidth, CPU, and memory on the Tomcat server. Note that

chunked transfer encoding is enabled by default. (CVE-2013-4322)

 

A denial of service flaw was found in the way Apache Commons FileUpload

handled small-sized buffers used by MultipartStream. A remote attacker

could use this flaw to create a malformed Content-Type header for a

multipart request, causing JBoss Web to enter an infinite loop when

processing such an incoming request. (CVE-2014-0050)

 

All Tomcat 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.

 

4. Solution:

 

Before applying this update, make sure all previously released errata

relevant to your system have been applied.

 

This update is available via the Red Hat Network. Details on how to use the

Red Hat Network to apply this update are available at

https://access.redhat.com/site/articles/11258
