Synopsis

Moderate: Red Hat JBoss Web Server 2.0.1 tomcat6 security update

Type/Severity

Security Advisory: Moderate

Topic

Updated tomcat6 packages that fix multiple security issues are now
available for Red Hat JBoss Web Server 2.0.1 on Red Hat Enterprise Linux 5
and 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.

Description

Red Hat JBoss Web Server is a fully integrated and certified set of
components for hosting Java web applications. It is comprised of the Apache
HTTP Server, the Apache Tomcat Servlet container, Apache Tomcat Connector
(mod_jk), JBoss HTTP Connector (mod_cluster), Hibernate, and the Tomcat
Native library.

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)

It was found that previous fixes in Tomcat 6 to path parameter handling
introduced a regression that caused Tomcat to not properly disable URL
rewriting to track session IDs when the disableURLRewriting option was
enabled. A man-in-the-middle attacker could potentially use this flaw to
hijack a user's session. (CVE-2014-0033)

A denial of service flaw was found in the way Apache Commons FileUpload,
which is embedded in Tomcat, 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 Tomcat to
enter an infinite loop when processing such an incoming request.
(CVE-2014-0050)

All users of Red Hat JBoss Web Server 2.0.1 are advised to upgrade to these
updated tomcat6 packages, which contain backported patches to correct these
issues. The Red Hat JBoss Web Server process must be restarted for the
update to take effect.

Solution

Before applying this update, make sure all previously released errata
relevant to your system have been applied, and back up your existing Red
Hat JBoss Web Server installation (including all applications and
configuration files).

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