Vendor: Hikvision

Description
The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists due to buffer overflow in the RTSP Packet Handler. A remote attacker can send a specially crafted packet using the Range parameter of the RTSP transaction, trigger memory corruption and cause the service to crash.

Successful exploitation of the vulnerability results in denial of service.

Mitigation
Install update from vendor's website.
