CVE-2018-3900

An exploitable code execution vulnerability exists in the QR code scanning functionality of Yi Home Camera 27US 1.8.7.0D. A specially crafted QR Code can cause a buffer overflow, resulting in code execution. An attacker can make the camera scan a QR code to trigger this vulnerability. Alternatively, a user could be convinced to display a QR code from the internet to their camera, which could exploit this vulnerability.
