The issue concerns multiple buffer overflows in the PocketNetNVRMediaClientAxCtrl.NVRMediaViewer.1 control, allowing remote attackers to execute arbitrary code. This can be achieved via a crafted string to various methods, including `StartRecord()`, `StartRecordEx()`, `StartScheduledRecord()`, `SetDisplayText()`, `GetONVIFDeviceInformation()`, `GetONVIFProfiles()`, and `GetONVIFStreamUri()`, or a crafted filename to `SaveCurrentImage()` or `SaveCurrentImageEx()`. No information is provided about the estimated number of potentially affected devices or real-world incidents.
