Apple and Oracle have released updates to Java to resolve this issue. Thus, the information in the "Guidance for End Users on Mac OS X" section is no longer necessary since the software updates should fully resolve the issue. Mac OS X users running Java 7 on Mac OS 10.7.3 and higher should follow instructions via the following Oracle site: http://www.java.com/en/download/faq/java_mac.xml
Mac OS X users running Java 6 on Mac OS 10.7.2 and lower should install a Java release provided by Apple. From the Apple menu, select Software Update. When prompted, install "Mac OS X 10.6 Update 12." This will update Java 6 to Update 39. See more information from Apple: http://support.apple.com/kb/DL1573
Vulnerability Overview On January 31, 2013, Apple pushed an update to its XProtect malware-handling system in Mac OS X. As a result, users on Mac OS X will not be able to run Java in their web browsers. Users on all versions of Java 6 (Update 37 and prior) and Java 7 (Update 11 and prior) are impacted. Apple has blocked users on Java 6 and Java 7 from using Apple XProtect without a public statement but it is likely doing so in anticipation of a Java 7 Update 12 release from Oracle to resolve a new undisclosed and unconfirmed security vulnerability. Though Java 6 Update 38 is available from Oracle, Apple has not made it available to its users and thus all versions of Java 6 are impacted. The latest version of Java 7 is Update 11 and thus all versions of Java 7 are impacted.
Java is necessary for various parts of the Blackboard Learning Management System software to run but the majority of application functionality is available. See the "Guidance for End Users" section for more information. To emphasize, this change only impacts end users on Mac OS X. End users on other operating systems are not impacted by this change from Apple. This update from Apple was used to block the current released version of Oracle Java 7 Update 11 and prior versions of Oracle Java 7 as part of a security measure to help ensure users are protected from attacks via the web browser.
Oracle Java 7 Update 11 was just released on January 13, 2013, as described by a previous Blackboard Learn Security Advisory and was previously released to fix two high severity vulnerabilities affecting Java 7 in web browsers. Blackboard will update this security advisory as more information becomes available. Customers may contact Apple and Oracle directly for more information on Apple and Oracle software update processes respectively.
