What is CVE-2018-3920?

A vulnerability exists in the firmware update functionality of the Yi Home Camera, specifically in version 27US 1.8.7.0D. This flaw can be exploited via a specially crafted 7-Zip file which can trigger a CRC collision. When the camera processes this manipulated file, it may initiate a firmware update allowing unauthorized code execution. An attacker could exploit this by inserting an SD card containing the malicious 7-Zip file, thereby gaining access to the device's firmware and potentially executing arbitrary code.
