The Clipboard::DispatchObject function in app/clipboard/clipboard.cc in Google Chrome before 5.0.375.70 does not properly handle CBF_SMBITMAP objects in a ViewHostMsg_ClipboardWriteObjectsAsync message, which might allow remote attackers to execute arbitrary code via vectors involving crafted data from the renderer process, related to a "Type Confusion" issue.
