"A specially crafted TCP/IP packet may cause a camera recovery image
telnet interface to crash. It may also cause a buffer overflow which
could enable remote code execution. The recovery image can only be
booted with administrative rights or with physical access to the
camera and allows the upload of a new firmware in case of a damaged
firmware.
