Bug ID: 251130
Summary: OffscreenCanvas::transferToImageBitmap doesn't
restrict enforce size restrictions
Product: WebKit
Version: WebKit Nightly Build
Hardware: Unspecified
OS: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: Canvas
Assignee: webkit-unassigned at lists.webkit.org
Reporter: mattwoodrow at apple.com
CC: dino at apple.com
We share code with HTMLCanvasElement via CanvasBase for allocating the backing store, with max size restrictions.
transferToImageBitmap can sometimes allocate a new buffer (if there isn't one already), and it currently isn't using the same code, so doesn't have the same restrictions.
