Buffer overflow in Hikvision DVR DS-7204 Firmware 2.2.10 build 131009, and other models and versions, allows remote attackers to execute arbitrary code via an RTSP PLAY request with a long Authorization header.
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.
