Description Sebastian Krahmer 2012-09-11 09:39:47 UTC
Public, via OSS-sec:


Hello Kurt, Steve, vendors,

  an information disclosure flaw was found in the way certain
Java Virtual Machines (JVM) used to initialize integer arrays
(they have had nonzero elements right after the allocation in
certain circumstances). An attacker could use this flaw to
obtain potentially sensitive information.

References (including the reproducer, workaround and further details):
[1] http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7196857
[2] https://bugzilla.redhat.com/show_bug.cgi?id=856124

Could you allocate a CVE id for this?

Thank you && Regards, Jan.

P.S#2: Oracle Security Team Cc-ed on this request too (to clarify
       if CVE id has been assigned to this already or not).

AFAIK, OpenJDK got a different identifier, it's CVE-2012-4420. Just to have
it documented clearly.
