Google Chrome contains an out-of-bounds read flaw in the RenderWidgetSnapshotTaker::WidgetDidReceivePaintAtSizeAck() function in browser/thumbnails/render_widget_snapshot_taker.cc, as the TransportDIB may not be sufficiently sized to "act as the pixel data for the SkBitmap". This may allow a context-dependent attacker to crash the browser and potentially disclose memory contents.
