Affected devices can be configured to send emails when certain events occur on the device. When presented with an invalid response from the SMTP server, the device triggers an error that disrupts email sending. An attacker with access to the network can use this to do disable notification of users when certain events occur.
The product does not check the return value from a method or function, which can prevent it from detecting unexpected states and conditions.
