CanvasRenderingContext2D.putImageData() should not process neutered ImageData https://bugs.webkit.org/show_bug.cgi?id=208303 Patch by Pinki Gyanchandani <pgyanchandani@apple.com> on 2020-03-25 Reviewed by Said Abou-Hallawa. Source/WebCore: Test: fast/canvas/canvas-putImageData-neutered-ImageData.html The crash happens when putImageData is called on a neutered ImageData object. Added a check to exit from CanvasRenderingContext2D.putImageData() function when ImageData object is neutered. * html/canvas/CanvasRenderingContext2DBase.cpp: (WebCore::CanvasRenderingContext2DBase::putImageData): LayoutTests: Added slightly modified version of testcase from bugzilla. This testcase checks that a neutered ImageData object is not considered to be put onto the canvas. * fast/canvas/canvas-putImageData-neutered-ImageData-expected.txt: Added. * fast/canvas/canvas-putImageData-neutered-ImageData.html: Added.
