<background>
|
||
|
<p>PHP is an open source general-purpose scripting language that is
|
||
|
especially suited for web development.

<description>
|
||
|
<p>A underflow in env_path_info in PHP-FPM under certain configurations can
|
||
|
be exploited to gain remote code execution.
|

<impact type="high">
|
||
|
<p>A remote attacker, by sending special crafted HTTP requests, could
|
||
|
possibly execute arbitrary code with the privileges of the process, or
|
||
|
cause a Denial of Service condition.
|
||
|
</p>

||
|
</impact>
|
||
|
<workaround>
|
||
|
<p>If patching is not feasible, the suggested workaround is to include
|
||
|
checks to verify whether or not a file exists before passing to PHP.

|
</p>
