Telegram fixes IP address leak in desktop client

Telegram users who specifically utilize the application for its anonymity features are advised to update their desktop clients as soon as possible to patch a bug that will leak their IP address in some scenarios. The bug was found by Dhiraj Mishra, a bug hunter from Mumbai, India, and was patched by Telegram with the releases of Telegram for Desktop v1.4.0 and v1.3.17 beta.

Mishra discovered that the Telegram desktop clients for Windows, Mac, and Linux would reveal users’ IP addresses. The leak happened only during voice calls. This is a dangerous bug, especially for users who utilize Telegram for its privacy and anonymity feature, such as journalists, political dissidents, or human rights fighters.
