It includes various bug fixes andenhancements, which are detailed in the Red Hat JBoss Data Grid 6.4.1Release Notes. The Release Notes are available at:https://access.redhat.com/documentation/en-US/RedHatJBossDataGrid/ This update also fixes the following security issues:It was found that a prior countermeasure in Apache WSS4J forBleichenbacher's attack on XML Encryption (CVE-2011-2487) threw anexception that permitted an attacker to determine the failure of theattempted attack, thereby leaving WSS4J vulnerable to the attack.The original flaw allowed a remote attacker to recover the entire plaintext form of a symmetric key. (CVE-2015-0226)A resource consumption issue was found in the way Xerces-J handled XMLdeclarations. A remote attacker could use an XML document with a speciallycrafted declaration using a long pseudo-attribute name that, when parsed byan application using Xerces-J, would cause that application to use anexcessive amount of CPU. (CVE-2013-4002)It was found that the RESTEasy DocumentProvider did not set theexternal-parameter-entities and external-general-entities featuresappropriately, thus allowing external entity expansion. A remote attackerable to send XML requests to a RESTEasy endpoint could use this flaw toread files accessible to the user running the application server, andpotentially perform other more advanced XML eXternal Entity (XXE) attacks.(CVE-2014-7839)It was found that Apache WSS4J permitted bypass of therequireSignedEncryptedDataElements configuration property via XML Signaturewrapping attacks. A remote attacker could use this flaw to modify thecontents of a signed request. (CVE-2015-0227)It was discovered that under specific conditions the conversation stateinformation stored in a thread-local variable in JBoss Weld was notsanitized correctly when the conversation ended. This could lead to a racecondition that could potentially expose sensitive information from aprevious conversation to the current conversation. (CVE-2014-8122)Red Hat would like to thank Rune Steinseth of JProfessionals for reportingthe CVE-2014-8122 issue.All users of Red Hat JBoss Data Grid 6.4.0 as provided from the Red HatCustomer Portal are advised to upgrade to Red Hat JBoss Data Grid 6.4.1.
