CVE-2009-1694 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-1694): WebKit in Apple Safari before 4.0, iPhone OS 1.0 through 2.2.1, and iPhone OS for iPod touch 1.1 through 2.2.1 does not properly handle redirects, which allows remote attackers to read images from arbitrary web sites via vectors involving a CANVAS element and redirection, related to a "cross-site image capture issue."
Presumably all affected versions are gone from tree. Closing as discussed with keytoaster.
