Possible to run arbitrary PHP code on pipermail server

[Remco]

I read the following e-mail on pipermail:
http://www.winehq.org/pipermail/wine-devel/2009-February/073428.html

Try downloading the PHP attachment from there; it will actually
execute and give you an HTML page. This could easily be abused!
