A remote buffer overflow vulnerability affects Stormy Studios KNet. This issue is due to a failure of the application to securely copy user-supplied input into finite process buffers.
|
|
|
|
An attacker may leverage this issue to execute arbitrary code on a computer with the privileges of the affected server, facilitating unauthorized access.
|
|
|
