Security Advisory: Important
Updated tomcat5 packages that fix three security issues are now available
for Red Hat Application Server v2.
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.
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)
Two directory traversal flaws were found in the Tomcat deployment process.
A specially-crafted WAR file could, when deployed, cause a file to be
created outside of the web root into any directory writable by the Tomcat
user, or could lead to the deletion of files in the Tomcat host's work
directory. (CVE-2009-2693, CVE-2009-2902)
Users of Tomcat should upgrade to these updated packages, which contain
backported patches to resolve these issues. Tomcat must be restarted for
this update to take effect.
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
