Hi everyone,

While reviewing the security policy for PHP I noticed a few gaps which I think 
are important to address.

At the moment I'd like to propose the following changes, so please comment and 
feel free to propose others:

To clarify that the policy applies to the interpreter and apps, which is how 
it has been treated so far.

To include unserialize() and ini settings such as short_open_tag. 

If there are no objections, I'm going to include that change in the next 
upload and make it the policy for Squeeze. Unless there's a reason to 
reconsider the policy applying lenny, it won't be updated to squeeze's.

Cheers,
