SignatureHandler-calloc.patch
Inside SignatureHandler.cc and specifically in
SignatureHandler::getSignerSubjectDN() the subjectName of cert is read and
returned back to validateSignature() of Form.cc and then to pdfsig.cc.
Returning to pdfsig.cc though signature_handler is destroyed and as a result
the pointer to subjectName is invalid. I am attaching a small patch that
allocates memory for subjectName before returning to avoid segfault but this
memory should be freed after usage. The patch attached is an example, not as a
patch to be merged to master :-)</pre>
