Updated tomcat6 packages that fix multiple security issues are nowavailable for Red Hat Enterprise Linux 6.The Red Hat Security Response Team has rated this update as havingimportant 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 withanother component that calls request.setUserPrincipal before the call toFormAuthenticator#authenticate , it waspossible to bypass the security constraint checks in the FORM authenticatorby appending "/j_security_check" to the end of a URL. A remote attackerwith an authenticated session on an affected application could use thisflaw to circumvent authorization controls, and thereby access resources notpermitted by the roles associated with their authenticated session.A flaw was found in the way Tomcat handled sendfile operations when usingthe HTTP NIO connector and HTTPS. A remote attackercould use this flaw to cause a denial of service . The HTTPblocking IO connector, which is not vulnerable to this issue, is usedby default in Red Hat Enterprise Linux 6. Multiple weaknesses were found in the Tomcat DIGEST authenticationimplementation, 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 correctthese issues. Tomcat must be restarted for this update to take effect.
