The fix

We hold no Microsoft remediation data for CVE-2012-0507, which normally means it is not a Windows CVE. For non-Microsoft software the fix is the vendor's own updated release, and the affected versions are listed below.

What it is

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.
