The difference is one is in src/deps/PDFWriter/PDFParser.cpp and the other is PDFDocumentHandler.cpp both is a null pointer but for different cases
These are totally diffent issues, one is in reading a pdf the other is in appendending a maliciously crafted one. The function calls are different the versions in which they are solved are diffent.
