JSON

GNU Mailman 2.x before 2.1.30 uses the .obj extension for scrubbed
application/octet-stream MIME parts. This behavior may contribute to XSS
attacks against list-archive visitors, because an HTTP reply from an
archive web server may lack a MIME type, and a web browser may perform MIME
sniffing, conclude that the MIME type should have been text/html, and
execute JavaScript code.
