2017-09-28Convert LZW decompressor to use vector instead of static arraychromium/3230chromium/3229chromium/3228chromium/3227Ryan Harrison
Speciifically replacing what was called the "stack_", an array, with a vector called "decompressed_". The fact that this data structure wasn't actually a stack caused a lot of grief when refactoring.

2017-09-28Fix infinite loop on form availability check.Artem Strygin
The problem was, that the CPDF_SyntaxParser read last block not from requested position. In this case It move down requested position to fill whole buffer. As result this additional data was not requested by DownloadHints. To fix this allow resize data buffer in CPDF_SyntaxParser, to store more small block, and always read from requsted position. Also add reading check into CPDF_Parser::LoadLinearizedMainXRefTable to prevent infinite loops.

If the global palette is disable, it will not have data, but it may have a size. Technically the size is giberish in this case, but the value is allowed to be non-zero, so isn't a sufficient check.

2017-09-22Fix crash when rendering invalid GIFRyan Harrison
The core fix in this CL is a change to how LWZ decompression works, so that when the min code table size and the color palette size are different, color codes after the end of the defined color palette are considered errors. This CL also introduces a bunch of tweaks to the call return path, since there were multiple locations where the GIF decode failing status was being dropped on the floor, so the end widget would have a bitmap with the default colour in it, instead of nothing.
