-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: JBoss Enterprise Portal Platform 4.3 CP07 update Advisory ID: RHSA-2012:0091-01 Product: JBoss Enterprise Middleware Advisory URL: https://rhn.redhat.com/errata/RHSA-2012-0091.html Issue date: 2012-02-02 CVE Names: CVE-2011-1184 CVE-2011-1484 CVE-2011-2526 CVE-2011-4085 CVE-2011-4858 CVE-2011-5062 CVE-2011-5063 CVE-2011-5064 ===================================================================== 1. Summary: JBoss Enterprise Portal Platform 4.3 CP07, which fixes multiple security issues and various bugs, is now available from the Red Hat Customer Portal. 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. 2. Description: JBoss Enterprise Portal Platform is the open source implementation of the Java EE suite of services and Portal services running atop JBoss Enterprise Application Platform. It comprises a set of offerings for enterprise customers who are looking for pre-configured profiles of JBoss Enterprise Middleware components that have been tested and certified together to provide an integrated experience. This JBoss Enterprise Portal Platform 4.3 CP07 release serves as a replacement for JBoss Enterprise Portal Platform 4.3 CP06. Refer to the JBoss Enterprise Portal Platform 4.3 CP07 Release Notes, available shortly from docs.redhat.com, for information on the most significant bug fixes included in this release. The following security fixes are also included: JBoss Seam 2 did not properly block access to JBoss Expression Language (EL) constructs in page exception handling, allowing arbitrary Java methods to be executed. A remote attacker could use this flaw to execute arbitrary code via a specially-crafted URL provided to certain applications based on the JBoss Seam 2 framework. Note: A properly configured and enabled Java Security Manager would prevent exploitation of this flaw. (CVE-2011-1484) Note: If you have created custom applications that are packaged with a copy of the JBoss Seam 2 library, those applications must be rebuilt with the updated jboss-seam.jar file provided by this update. It was found that the Java hashCode() method implementation was susceptible to predictable hash collisions. A remote attacker could use this flaw to cause JBoss Web to use an excessive amount of CPU time by sending an HTTP request with a large number of parameters whose names map to the same hash value. This update introduces a limit on the number of parameters and headers processed per request to mitigate this issue. The default limit is 512 for parameters and 128 for headers. These defaults can be changed by setting the org.apache.tomcat.util.http.Parameters.MAX_COUNT and org.apache.tomcat.util.http.MimeHeaders.MAX_COUNT system properties in "server/$PROFILE/deploy/properties-service.xml". (CVE-2011-4858) Multiple flaws were found in the way JBoss Web handled HTTP DIGEST authentication. These flaws weakened the JBoss Web HTTP DIGEST authentication implementation, subjecting it to some of the weaknesses of HTTP BASIC authentication, for example, allowing remote attackers to perform session replay attacks. (CVE-2011-1184, CVE-2011-5062, CVE-2011-5063, CVE-2011-5064) The invoker servlets, deployed by default via httpha-invoker, only performed access control on the HTTP GET and POST methods, allowing remote attackers to make unauthenticated requests by using different HTTP methods. Due to the second layer of authentication provided by a security interceptor, this issue is not exploitable on default installations unless an administrator has misconfigured the security interceptor or disabled it. (CVE-2011-4085) A flaw was found in the way JBoss Web handled sendfile request attributes when using the HTTP APR (Apache Portable Runtime) or NIO (Non-Blocking I/O) connector. A malicious web application running on a JBoss Web instance could use this flaw to bypass security manager restrictions and gain access to files it would otherwise be unable to access, or possibly terminate the Java Virtual Machine (JVM). (CVE-2011-2526) Red Hat would like to thank Martin Kouba from IT SYSTEMS a.s. for reporting CVE-2011-1484; oCERT for reporting CVE-2011-4858; and the Apache Tomcat project for reporting CVE-2011-2526. oCERT acknowledges Julian Wälde and Alexander Klink as the original reporters of CVE-2011-4858. Warning: Before applying this update, back up all applications deployed on JBoss Enterprise Portal Platform, along with all customized configuration files. All users of JBoss Enterprise Portal Platform 4.3 CP06 as provided from the Red Hat Customer Portal are advised to upgrade to JBoss Enterprise Portal Platform 4.3 CP07. 3. Solution: The References section of this erratum contains a download link (you must log in to download the update). The JBoss server process must be restarted for this update to take effect. Note that if you have created custom applications that are packaged with a copy of the JBoss Seam 2 library, those applications must be rebuilt with the updated jboss-seam.jar file provided by this update. 4.
