Description

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. The trans_info call can overwrite a buffer of size 0x104, which is more than enough to overflow the return address from the ssid_dst field.
