Multiple buffer overflows in the PocketNetNVRMediaClientAxCtrl.NVRMediaViewer.1 control in 3S Pocketnet Tech VMS allow remote attackers to execute arbitrary code via a crafted string to the (1) StartRecord, (2) StartRecordEx, (3) StartScheduledRecord, (4) SetDisplayText, (5) GetONVIFDeviceInformation, (6) GetONVIFProfiles, or (7) GetONVIFStreamUri method or a crafted filename to the (8) SaveCurrentImage or (9) SaveCurrentImageEx method.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
