Integer overflow in the Tapo C200 V3 HTTPS server before 1.4.5 Build 251104 allows remote attackers to crash the camera. The server accepts a crafted Content-Length value without adequate validation, overflows an integer, and attempts an excessive memory allocation. Access to the same local network segment is required, and the resulting crash has no reported confidentiality or integrity impact.
