CVE-2017-18667

Name of the Vulnerable Software and Affected Versions: Samsung mobile devices with Android versions 4.4 through 7.x

Description: An issue allows attackers to prevent users from learning that SMS storage space has been exhausted on affected devices.

Recommendations: For Android version 4.4, update the SMS storage management to properly notify users when storage space is exhausted. For Android version 5.0/5.1, modify the SMS app to alert users when the storage limit is reached. For Android version 6.0, adjust the system settings to display a notification when SMS storage is full. For Android version 7.x, change the default behavior to warn users before the SMS storage space is exhausted. As a temporary workaround, consider restricting the number of SMS messages that can be stored on the device until a proper fix is applied.
