Potential jail escape vulnerabilities in netmap

A user-provided integer option was passed to nmreq_copyin() without checking if it would overflow. This insufficient bounds checking could lead to kernel memory corruption.

Multiple models of the Uniview IP Camera (e.g., IPC_G6103 B6103.16.10.B25.201218, IPC_G61, IPC21, IPC23, IPC32, IPC36, IPC62, and IPC_HCMN) offer an undocumented UDP service on port 7788 that allows a remote unauthenticated attacker to overflow an internal buffer and achieve code execution. By using this buffer overflow, a remote attacker can start the telnetd service. This service has a hardcoded default username and password (root/123456). Although it has a restrictive shell, this can be easily bypassed via the built-in ECHO shell command.

A buffer overflow in the RTSP service of the Ambarella Oryx RTSP Server 2020-01-07 allows an unauthenticated attacker to send a crafted RTSP request, with a long digest authentication header, to execute arbitrary code in parse_authentication_header() in libamprotocol-rtsp.so.1 in rtsp_svc (or cause a crash). This allows remote takeover of a Furbo Dog Camera, for example. NOTE: The vendor states that the RTSP library is used for DEMO only, using it in product is a customer's behavior. Ambarella has emphasized that RTSP is DEMO only library, should NOT be used in product in our document. Because Ambarella's SDK is proprietary, we didn't publish our SDK source code in public network.
