Description: Several vulnerabilities were reported in PHP. A remote user can conduct cross-site scripting attacks. Other security related flaws were reported but the impact was not specified.
The phpinfo() function does not properly filter HTML code from user-supplied input before displaying the input. For scripts that
invoke phpinfo(), a user can cause arbitrary scripting code to be executed by the target user's browser. The code will originate
from the site running the Php software and will run in the security context of that site. As a result, the code will be able to
access the target user's cookies (including authentication cookies), if any, associated with the site, access data recently submitted
by the target user via web form to the site, or take actions on the site acting as the target user.
A user may be able to trigger
a buffer overflow in the wordwrap() function. The impact was not specified.
A user may be able to trigger a heap corruption
within the session extension. The impact was not specified.
A user may be able to cause a variable to persist after the unset()
function is called. The impact was not specified.

Impact: In some cases, a user can access the target user's cookies (including authentication cookies), if any, associated with the site running
the PHP software, access data recently submitted by the target user via web form to the site, or take actions on the site acting
as the target user.
The specific impact depends on the applications that use PHP.
The impact of the other vulnerabilities
was not disclosed.
