PHP is a widely-used general-purpose scripting language that is
|
|
especially suited for Web development and can be embedded into HTML.

|
|
The sscanf() PHP function contains an array boundary error that can be
|
|
exploited to dereference a null pointer. This can possibly allow the
|
|
bypass of the safe mode protection by executing arbitrary code.

<impact type="normal">
|
|
<p>
|
|
A remote attacker might be able to exploit this vulnerability in PHP
|
|
applications making use of the sscanf() function, potentially resulting
|
|
in the execution of arbitrary code or the execution of scripted
|
|
contents in the context of the affected site.
