TrueConf Client Update Integrity Verification Bypass

TrueConf Client downloads updates without checking if they're genuine, allowing attackers to inject malicious code if they can intercept the download. This can lead to complete compromise of the user's system.

The application fails to cryptographically verify update integrity before execution, creating an arbitrary code execution vulnerability. An attacker with network-level access (e.g., MITM) can replace legitimate updates with malicious payloads, executing code with the privileges of the update process or logged-in user.
