2017-10-10Fix dangling pointer to ID array in CPDF_SecurityHandler.chromium/3238chromium/3237Henrique Nakashima
This was caused by breaking the reference from CPDF_SecurityHandler to CPDF_Parser in https://pdfium-review.googlesource.com/c/pdfium/+/15290 The reference was replaced with a reference to the ID Array and a copy of the password. The issue is that when parsing PDFs with multiple trailers, the trailer containing the ID array may be replaced and destroyed in CPDF_Parser::TrailerData::SetMainTrailer() after being passed to CPDF_SecurityHandler, which would then have a dangling pointer to it. This CL changes the CPDF_SecurityHandler to hold a copy of the original file ID instead of all the ID Array.
