-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: JBoss Web Services security update Advisory ID: RHSA-2013:1143-01 Product: Red Hat JBoss Middleware Advisory URL: https://rhn.redhat.com/errata/RHSA-2013-1143.html Issue date: 2013-08-07 CVE Names: CVE-2012-5575 ===================================================================== 1. Summary: An update for the JBoss Web Services component in Red Hat JBoss SOA Platform 4.3 CP05 and Red Hat JBoss Portal 4.3 CP07 which fixes one security issue is now available from the Red Hat Customer Portal. The Red Hat Security Response Team has rated this update as having important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. 2. Description: Red Hat JBoss SOA Platform is the next-generation ESB and business process automation infrastructure. Red Hat JBoss Portal is the open source implementation of the Java EE suite of services and Portal services running atop Red Hat JBoss Enterprise Application Platform. XML encryption backwards compatibility attacks were found against various frameworks, including Apache CXF. An attacker could force a server to use insecure, legacy cryptosystems, even when secure cryptosystems were enabled on endpoints. By forcing the use of legacy cryptosystems, flaws such as CVE-2011-1096 and CVE-2011-2487 would be exposed, allowing plain text to be recovered from cryptograms and symmetric keys. This issue only affected the JBoss Web Services Native (jbossws-native) stack as Red Hat JBoss SOA Platform 4 and Red Hat JBoss Portal 4 do not use JBoss Web Services CXF (jbossws-cxf). (CVE-2012-5575) For jbossws-native, the fix for CVE-2012-5575 is implemented by two new configuration parameters in the 'encryption' element. This element can be a child of 'requires' in both client and server wsse configuration descriptors (set on a per-application basis via the application's jboss-wsse-server.xml and jboss-wsse-client.xml files). The new attributes are 'algorithms' and 'keyWrapAlgorithms'. These attributes should contain a blank space or comma separated list of algorithm IDs that are allowed for the encrypted incoming message, both for encryption and private key wrapping. For backwards compatibility, no algorithm checks are performed by default for empty lists or missing attributes. For example (do not include the line break in your configuration): encryption algorithms="aes-192-gcm aes-256-gcm" keyWrapAlgorithms="rsa_oaep" Specifies that incoming messages are required to be encrypted, and that the only permitted encryption algorithms are AES-192 and 256 in GCM mode, and RSA-OAEP only for key wrapping. Before performing any decryption, the jbossws-native stack will verify that each algorithm specified in the incoming messages is included in the allowed algorithms lists from these new encryption element attributes. The algorithm values to be used for 'algorithms' and 'keyWrapAlgorithms' are the same as for 'algorithm' and 'keyWrapAlgorithm' in the 'encrypt' element. After applying this update, an "org.xml.sax.SAXParseException: DOCTYPE is disallowed..." error may occur when using transactions. To work around this issue, add -Dorg.jboss.ws.enable_doctype_decl=true to the application server's run parameters. Also, for users of Red Hat JBoss SOA Platform 4.3 CP05, after installing this update, ensure any @BindingType annotations in your deployed applications are updated to be applied to the relevant service implementations rather than the interfaces. Red Hat would like to thank Tibor Jager, Kenneth G. Paterson and Juraj Somorovsky of Ruhr-University Bochum for reporting CVE-2012-5575. Warning: Before applying this update, back up your JBoss installation, including any databases, database settings, applications, configuration files, and so on. All users of Red Hat JBoss SOA Platform 4.3 CP05 and Red Hat JBoss Portal 4.3 CP07 as provided from the Red Hat Customer Portal are advised to apply this update. 3. Solution: The References section of this erratum contains download links (you must log in to download the update). Before applying this update, back up your JBoss installation, including any databases, database settings, applications, configuration files, and so on. For both Red Hat JBoss SOA Platform and Red Hat JBoss Portal, it is recommended to halt the server by stopping the JBoss Application Server process before installing this update, and then after installing the update, restart the server by starting the JBoss Application Server process. After applying this update, an "org.xml.sax.SAXParseException: DOCTYPE is disallowed..." error may occur when using transactions. To work around this issue, add -Dorg.jboss.ws.enable_doctype_decl=true to the application server's run parameters. Also, for users of Red Hat JBoss SOA Platform 4.3 CP05, after installing this update, ensure any @BindingType annotations in your deployed applications are updated to be applied to the relevant service implementations rather than the interfaces. 4.
