Summary
Red Hat Security Advisory: tomcat5 security update

Notes

Topic
Updated tomcat5 packages that fix three security issues are now available for Red Hat Certificate System 7.3. 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.
Details
Apache Tomcat is a servlet container for the Java Servlet and JavaServer Pages (JSP) technologies. A flaw was found in the way Tomcat handled the Transfer-Encoding header in HTTP requests. A specially-crafted HTTP request could prevent Tomcat from sending replies, or cause Tomcat to return truncated replies, or replies containing data related to the requests of other users, for all subsequent HTTP requests. (CVE-2010-2227) This erratum fixes two additional security flaws in Tomcat. In a typical operating environment, Tomcat is not exposed to users of Red Hat Certificate System in a vulnerable manner. These fixes will reduce risk in unique Certificate System environments. (CVE-2009-2693, CVE-2009-2902) Users of Red Hat Certificate System 7.3 should upgrade to these updated tomcat5 packages, which contain backported patches to correct these issues. After installing the updated packages, the Red Hat Certificate System CA (rhpki-ca), DRM (rhpki-kra), OCSP (rhpki-ocsp), and TKS (rhpki-tks) subsystems must be restarted ("/etc/init.d/[instance-name] restart") for this update to take effect.
