2016-08-09Fixup various overflow conditionsdsinclair
There were several overflows detected by the PDF from the linked bug. This Cl fixes up the base causes of each of them. BUG=chromium:635473 Review-Url: https://codereview.chromium.org/2226023002
2016-08-08Add CPDF_Array::IsEmpty().jaepark
Using IsEmpty() is more readable than using GetCount() == 0. Review-Url: https://codereview.chromium.org/2226113002
2016-08-08Check if image width or height are zero before proceeding.dsinclair
If the width of the CJBig2_Image is set to 0 then the stride_pixels will be zero and when we divide we'll get a floating point exception. If the width or height are zero then we can exit early without proceeding with the rest of the constructor. BUG=chromium:635008 Review-Url: https://codereview.chromium.org/2222843004
2016-08-08Move CFX_ClipRgn and CFX_PathData into their own files.npm
This is the second CL in an attempt to split up the classes in fxge/include/fx_ge.h into their own files. CFX_ClipRgn is moved to core/fxge/ge because it is only used in core/fxge. The header for CFX_PathData is left in core/fxge/include since it is used elsewhere. Review-Url: https://codereview.chromium.org/2216853004

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
2016-08-02Verify row bytes before alloc in BMP codec.dsinclair
If the out_row_bytes is negative the alloc will fail. Verify the size before alloc and bail if it's negative. BUG=633381 Review-Url: https://codereview.chromium.org/2202283003
2016-08-02Use PaintOperation instead of bFillOrStroke in CPVT_GenerateAP.jaepark

2016-07-28Split fpdfdoc/include/fpdf_doc.h into individual classes.dsinclair
This CL splits the header file apart. The cpp files are not touched as part of this CL, they will be done as a followup. This de-duplicates the fpdf_doc.h BUG=pdfium:249 Review-Url: https://codereview.chromium.org/2183313004
2016-07-28fix text matrix againcaryclark
The text matrix for Skia is still wrong. The last fix allowed text to draw correctly when rotated, but did not draw correctly when skewed. With this edit, text draws correctly rotated, skewed horizontally, skewed vertically, and rotated and skewed. R=dsinclair@chromium.org Review-Url: https://codereview.chromium.org/2189093002
2016-07-27Fixup integer conversion logic.chromium/2813chromium/2812chromium/2811dsinclair
In bc8a64029f898286c3dcad3a6cecdc98ef30b139 we updated the FX_atonum logic to correctly handle integer overflow. This causes issues when parsing the Permissions flag of encrypted documents as that flag isn't encoded like other numbers. The Permissions flag is a unsigned value, and has to be treated as such since the sign bit is always set. The current logic will detect an overflow of the int value and return 0. The old logic would have detected the overflow and returned the negative result regardless. This CL updates the logic to do the string to int conversion as a uint32_t and then verifies the uint32_t value, if a sign was provided, fits within the int range, otherwise it converts it to an int and lets it be positive or negative as needed.

2016-07-27Splitting fx_ge_fontmap.cppnpm
Move CFX_FolderFontInfo, CFX_FontMgr, and CFX_FontMapper into their own classes. There are namespaces in each of the new files, having methods from the original namespace in fx_ge_fontmap, according to what each class needs. Review-Url: https://codereview.chromium.org/2185533006
2016-07-26Use smart pointer for CPDF_Form in CPDF_Annot.jaepark

2016-07-24Remove CFX_Deletableweili
Change the last use of CFX_Deletable to its actual type and remove the use of CFX_Deletable. Review-Url: https://codereview.chromium.org/2178613002
2016-07-24Use actual type instead CFX_Deletableweili
Change two places that used CFX_Deletable to use actual types. This makes the type more obvious, and avoids unnecessary casts. Review-Url: https://codereview.chromium.org/2180443002
