CVE-2009-1598

Google Chrome executes DOM calls in response to a javascript: URI in the
target attribute of a submit element within a form contained in an inline
PDF file, which might allow remote attackers to bypass intended Adobe
Acrobat JavaScript restrictions on accessing the document object, as
demonstrated by a web site that permits PDF uploads by untrusted users, and
therefore has a shared document.domain between the web site and this
javascript: URI. NOTE: the researcher reports that Adobe’s position is “a
PDF file is active content.”
