Timo Boehme closed PDFBOX-1212.
-------------------------------
Resolution: Fixed
Fix Version/s: 1.7.0
fixed in rev. 1234846; o.a.p.pdmodel.encryption.SecurityHandler scans for
dictionaries which might be signature dictionaries because the strings of
'Content' field should not be changed; the problem arises if the dictionary
traversal points to objects in object streams because these are not available
at this point, thus we have to check for null values and stop traversal here;
Since (byte range) signature dictionaries with string valued Content field
won't be in object streams, adding the traversal stop does not produce another
problem.
