2017-10-25Enforce end of data in CJBig2_ArithDecoderNicolas Pena
Quoting the JBIG2 spec: "If B is a 0xFF byte, then B1 (the byte pointed to by BP+1) is tested. If B1 exceeds 0x8F, then B1 must be one of the marker codes. The marker code is interpreted as required, and the buffer pointer remains pointed to the 0xFF prefix of the marker code which terminates the arithmetically compressed data. 1-bits are then fed to the decoder until the decoding is complete. This is shown by adding 0xFF00 to the C-register and setting the bit counter CT to 8." Our implementation is the alternative (faster for software according to the spec), where only CT is changed to 8. Reaching this part of the code means we will never read from stream again so we should be wrapping up the decoding. To ensure this, the |m_Complete| attribute is set to true if we reach this code again, which will result in bailing out next time DECODE is called.

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.

Fixed issue with unit tests that was causing raw data to be backwards and reverted related LSB -> MSB change that was introduced due to this. If global palette not set then the background colour index should be 0. Check that background colour index is valid when global palette exists. Check if transparency index is valid for the palette of the frame it is being applied to.
