2016-12-14Avoid the ptr.reset(new XXX()) anti-patterntsepez
Be suspicious of |new|. This removes some of the easy cases. Review-Url: https://codereview.chromium.org/2571913002
2016-12-12Fix JBig2 decoding logicweili
While decoding among instances, variable "FIRSTS" should hold its value, not be reset. This was accidently changed by earlier refactoring. BUG=chromium:625848,pdfium:636 Review-Url: https://codereview.chromium.org/2569023002
2016-11-09Add early returns in CJBig2_TRDProc::decode_Arith when decode fails.npm
None of the decodes in the method are currently being checked. This is causing pdfium to take a long time rendering corrupted files. Thus, I added a couple of early returns to help prevent this from happening. BUG=450971 Review-Url: https://codereview.chromium.org/2493633002

2016-08-02Bound total pixels in JBig2 images to avoid overflows later.tsepez
Also make these private to ensure they aren't modified so as to violate the bounds checks applied at creation time. BUG=633002 Review-Url: https://codereview.chromium.org/2202013002
2016-06-07Verify we have a CJBig2_Image before attempting use.dsinclair
In CJBig2_SDDProc::decode_Arith we will set a SDNEWSYMS value to nullptr if the height or width are 0. With the PDF from the bug, all of the decoders are set to nullptr. Then, we call into CJBig2_TRDProc::decode_Arith and pull out one of the nullptr decoders and attempt to use it, crashing. This CL adds a check that we have a non-null decoder before attempting to use the decoder. BUG=pdfium:511 Review-Url: https://codereview.chromium.org/2048683002
