Updated tomcat5 packages that fix multiple security issues are nowavailable for Red Hat Enterprise Linux 5. The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System basescores, which give detailed severity ratings, are available for eachvulnerability from the CVE links in the References section. Apache Tomcat is a servlet container. It was found that when an application used FORM authentication, along with another component that calls request.setUserPrincipal before the call toFormAuthenticator#authenticate , it was possible to bypass the security constraint checks in the FORM authenticator by appending "/j_security_check" to the end of a URL. A remote attacker with an authenticated session on an affected application could use this flaw to circumvent authorization controls, and the reby access resources notpermitted by the roles associated with their authenticated session. Multiple weaknesses were found in the Tomcat DIGEST authentication implementation, effectively reducing the security normally provided byDIGEST authentication. A remote attacker could use these flaws to performreplay attacks in some circumstances. Users of Tomcat should upgrade to these updated packages, which correct these issues. Tomcat must be restarted for this update to take effect.
