CVE-2012-0507

Unspecified vulnerability in the Java Runtime Environment (JRE) component
in Oracle Java SE 7 Update 2 and earlier, 6 Update 30 and earlier, and 5.0
Update 33 and earlier allows remote attackers to affect confidentiality,
integrity, and availability via unknown vectors related to Concurrency.
NOTE: the previous information was obtained from the February 2012 Oracle
CPU. Oracle has not commented on claims from a downstream vendor and third
party researchers that this issue occurs because the AtomicReferenceArray
class implementation does not ensure that the array is of the Object[]
type, which allows attackers to cause a denial of service (JVM crash) or
bypass Java sandbox restrictions. NOTE: this issue was originally mapped
to CVE-2011-3571, but that identifier was already assigned to a different
issue.
