@ian_dunn: The logo GUIDs have been removed in master. So presumably this issue
(whether it actually is one or not) will not exist anymore in PHP 5.5.

I agree with mhaisley, this is a security vulnerability and should be disabled
by
default. Many PCI compliance scanners will fail a site if it is turned on.
I realize that it's not a major vulnerability, but it does give attackers
information that could help them compromise a system. What are the benefits of
having it enabled by default? I can't think of any significant ones. Whatever
benefits there are, they'd have to outweigh the downsides, and that doesn't
seem
likely in this case.

Nope - this is not a bug.
Just disable it in your config file.

Sorry, but it is a real issue.
It should be disabled by default.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php
Attackers can easily brute force without knowing the version. But if youfear
this makes things insecure you can set expose_php=Off in php.ini.

Description:
------------
?=PHPB8B5F2A0-3C92-11d3-A3A9-4C7B08C10000 displays php credits, it also
displays
credits for all modules.
This effectively makes it a security issue since it allows an attacker to scan
for
a specific vulnerable module and then exploit it.
Test script:
---------------
http://php.net/?=PHPB8B5F2A0-3C92-11d3-A3A9-4C7B08C10000
Expected result:
----------------
?=PHPB8B5F2A0-3C92-11d3-A3A9-4C7B08C10000 should be disabled by default, or
display generic information only. The current behavior is unacceptable.
Actual result:
--------------
Specific information regarding installed modules is displayed.
