Using Blended Browser Threats involving Chrome to steal files on your computer

Inferno · securethoughts.com

CVE-2009-3931. Chrome auto-downloads files sent with Content-Disposition attachment and warns only on blacklisted extensions; .mht, .mhtml and .svg were absent from that list. Clicking the downloaded file opens it in IE6 or Safari from a local origin, where its script reads arbitrary local files. Google fixed it by extending the blacklist in v3.0.195.32.
