Crash in PDF_DataDecode (core/src/fpdfapi/fpdf_parser/fpdf_parser_decode.cpp) #3

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
The line
ParamList.Add(pParams->GetDict()); 
may crash if pParams is NULL. This could happen, if pDict parameter has Filter 
property of type PDFOBJ_NAME but doesn't have DecodeParms property.

if pParams is NULL, GetDict in fpdf_parser_objects.cpp:146 can check this 
situation and return NULL.
