An updated tomcat package that fixes several security issues is now available for Red Hat Network Satellite Server 5.1. This update has been rated as having low security impact by the Red Hat Security Response Team.
Apache Tomcat is a servlet container for the Java Servlet and JavaServer Pages (JSP) technologies. This update corrects several security vulnerabilities in the Tomcat component shipped as part of Red Hat Network Satellite Server. In a typical operating environment, Tomcat is not exposed to users of Satellite Server in a vulnerable manner: By default, only Satellite Server applications are running on Tomcat. This update will reduce risk in unique Satellite Server environments. It was discovered that request dispatchers did not properly normalize user requests that have trailing query strings, allowing remote attackers to send specially-crafted requests that would cause an information leak. (CVE-2008-5515) A flaw was found in the way the Tomcat AJP (Apache JServ Protocol) connector processes AJP connections. An attacker could use this flaw to send specially-crafted requests that would cause a temporary denial of service. (CVE-2009-0033) It was discovered that web applications containing their own XML parsers could replace the XML parser Tomcat uses to parse configuration files. A malicious web application running on a Tomcat instance could read or, potentially, modify the configuration and XML-based data of other web applications deployed on the same Tomcat instance. (CVE-2009-0783) Users of Red Hat Network Satellite Server 5.1 are advised to upgrade to this updated tomcat package, which contains backported patches to resolve these issues. Tomcat must be restarted for this update to take effect.
