===================================================================== Red Hat Security Advisory
Synopsis: Important: tomcat6 security and bug fix update Advisory ID: RHSA-2011:0335-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2011-0335.html Issue date: 2011-03-09 CVE Names: CVE-2010-4476 CVE-2011-0534 =====================================================================
1. Summary:
Updated tomcat6 packages that fix two security issues and one bug are now available for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having important 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 Red Hat Enterprise Linux Workstation Optional (v. 6) - noarch
3. Description:
Apache Tomcat is a servlet container for the Java Servlet and JavaServer Pages (JSP) technologies.
A denial of service flaw was found in the way certain strings were converted to Double objects. A remote attacker could use this flaw to cause Tomcat to hang via a specially-crafted HTTP request. (CVE-2010-4476)
A flaw was found in the Tomcat NIO (Non-Blocking I/O) connector. A remote attacker could use this flaw to cause a denial of service (out-of-memory condition) via a specially-crafted request containing a large NIO buffer size request value. (CVE-2011-0534)
This update also fixes the following bug:
* A bug in the "tomcat6" init script prevented additional Tomcat instances from starting. As well, running "service tomcat6 start" caused configuration options applied from "/etc/sysconfig/tomcat6" to be overwritten with those from "/etc/tomcat6/tomcat6.conf". With this update, multiple instances of Tomcat run as expected. (BZ#676922)
Users of Tomcat should 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.
