QK SMTP Remote Buffer Overflow Vulnerability

QK SMTP is prone to a remote buffer-overflow vulnerability because the application fails to bounds-check user-supplied data before copying it into an insufficiently sized buffer.

An attacker can exploit this issue to execute arbitrary code in the context of the affected application. This may facilitate a remote-compromise of affected computers. Failed exploit attempts will likely crash the server, effectively denying service to legitimate users.

QK SMTP 3.01 and prior versions are vulnerable to this issue.
