Description
Fuzzing PDF loading with JQF triggered a ClassCastException. All attached files trigger the exception for a different class but are basically the same.
org.apache.pdfbox.cos.COSArray cannot be cast to org.apache.pdfbox.cos.COSObject java.lang.ClassCastException: org.apache.pdfbox.cos.COSArray cannot be cast to org.apache.pdfbox.cos.COSObject at org.apache.pdfbox.pdfparser.COSParser.checkPagesDictionary(COSParser.java:2337) at org.apache.pdfbox.pdfparser.COSParser.checkPages(COSParser.java:2321) at org.apache.pdfbox.pdfparser.PDFParser.initialParse(PDFParser.java:193) at org.apache.pdfbox.pdfparser.PDFParser.parse(PDFParser.java:220) at org.apache.pdfbox.pdmodel.PDDocument.load(PDDocument.java:1160) at org.apache.pdfbox.pdmodel.PDDocument.load(PDDocument.java:1057) ...
The Code used for fuzzing is
PDDocument.load(inputStream)
Throwing an Exception is ok since no other PDF reader I tried is able to load the files. But it should not be an ClassCastException.
