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
5. Bugs fixed (https://bugzilla.redhat.com/):
1062337 - CVE-2014-0050 apache-commons-fileupload: denial of service due to too-small buffer size used by MultipartStream
1069905 - CVE-2013-4322 tomcat: incomplete fix for CVE-2012-3544
1069921 - CVE-2013-4286 tomcat: multiple content-length header poisoning flaws
