WinUAE is prone to a local stack-based buffer-overflow vulnerability because it fails to properly bounds-check user-supplied data before copying it to an insufficiently sized memory buffer.
|
|
|
|
An attacker can exploit this issue to execute arbitrary code in the context of the affected application. Failed exploit attempts will result in denial-of-service conditions.
|
|
|
|
This issue affects versions prior to WinUAE 1.4.5.
