Overview
Affected versions of this package are vulnerable to Stack-based Buffer Overflow in the RunSbieCtrl handler of SbieIniServer due to copying the message payload into a fixed-size stack buffer without verifying its length. An attacker can execute arbitrary code with SYSTEM privileges or cause a denial of service by sending an oversized payload through the service pipe, which is accessible to any local interactive process due to a NULL DACL.
