Local fix

Problem summary

  • Internally the Java Security DerValue class stores its
    der-encoded data within a DerInputStream object.
    Various DerValue methods read the contents of this
    DerInputStream to extract that data and perform their
    processing.  When multiple threads are simultaneously accessing
    these DerValue methods, serialized access to the
    DerInputStream is required. Otherwise the current read position
    in the stream can be unexpectedly modified for
    thread A by thread B.  Within most DerValue methods, that
    serialization logic was already present.  Within one
    method it was missing.
    

Problem conclusion

  • This defect will be fixed in:
    1.4.2 SR13 FP11
    5.0.0 SR13
    6.0.0 SR10
    .
    The missing serialization logic was added.
    .
    To obtain the fix:
    Install build 20110609 or later
