Well...

1) The relation to MIME-Types is only a _previous_ one... when the MIME
type definition from the mime-support package was used to get php files
interpreted.


2) Ondrej, I've already planned to suggest you... to change the
_handler_ name "application/x-httpd-php" that we now use throughout the
packages to someting like "php-script"...
It easily confuses people that this would be a MIME type,... while it is
actually a handler.

3) Yes, that's the case...
In principle we tried to explain in the NEWS file what has happened,...
obviously we cannot cover _any_ possible setup where this could occur
somehow; there are simply way too much possible and complex
configurations

In principle "you" as an administrator are expected to understand how
your own setup works,... raise your head when you read that NEWS
file.... and realise that you could be affected.

Yeah... that seems to be the case...

Seems so...

Mhh... well... perhaps as a small hint; in principle this is rather the
duty of the libapache2-mod-fcgid package.


The best thing would be obviously if one could make everything work out
of the box,... but I guess that's not really possibly... as one can
imagine setups where a mixture of CGI/FCGID/mod_php/FastCGI is used.

Further I would vote against an automatically installed config snippet
which globally sets SetHandler fcgid-script, as this (AFAIU) already
enables PHP/FCGID interpretation.



Has anyone an idea whether mod_fastcgi (!= mod_fcgid) is also affected?


Cheers,
Chris.


btw:
This:
FCGIWrapper  /usr/bin/php-cgi .php
may (I haven't checked) be vulnerable to the foo.php.jpeg issue.
