Assuming it a single fix, there should be a patch in the subversion archive
which addresses just this issue. The trick is going to be identifying it ;-)
There are ~200 revisions between 8187 and the released 8.61. I did find
three possible patches, one relating to PDF 1.5 security, one relating to
PDF 1.6 security (128-bit AES), the other to potentially invalidly secured
PDF files.
See bugs #688958, #688880, #687326. Your issue of course may not be any of
those...
When you say 'secured' what level of protection and what kind of security
has been applied ? Do you have an example file to look at ?
