CVE-2014-4262 OpenJDK: AtomicReferenceFieldUpdater missing primitive type check (Libraries, 8039520)
Last modified: 2015-07-29 09:56:05 EDT
Florian Weimer discovered that AtomicReferenceFieldUpdater in OpenJDK does not properly check if the field to be updated is of primitive type. An untrusted Java application or applet could use flaw to trigger Java virtual machine memory corruption and possibly bypass Java sandbox restrictions. AtomicReferenceFieldUpdater API documentation: http://docs.oracle.com/javase/7/docs/api/java/util/concurrent/atomic/AtomicReferenceFieldUpdater.html This issue is mitigated by the bug that prevents Atomic*FieldUpdater instances when code runs under security manager restrictions under OpenJDK and Oracle JDK 6 and 7. The bug was fixed in JDK8: http://bugs.java.com/bugdatabase/view_bug.do?bug_id=7103570 http://bugs.java.com/bugdatabase/view_bug.do?bug_id=7131655 http://hg.openjdk.java.net/jdk8/tl/jdk/rev/48513d156965 Acknowledgement: This issue was discovered by Florian Weimer of Red Hat Product Security.
