[geomoose-psc] PHP file system traversal vulnerability.

[TC Haddad]

Hey Dan,

FWIW, the text of your proposed email looks good. I think you could replace
the three references to 'bug' with 'security issue' and that is more likely
to get people's attention / quick action.

I feel like when there are security releases in other projects, the
information on the users list is kept to a minimum - just the facts of the
release, relevant download links, and not a lot of info on the nature of
the exploit.

So given that you could even just end your first paragraph after "earlier
versions of the 2.X series may also be affected."... if you think that's
enough detail.

Tanya
