漏洞描述

The Onion module in toxcore before 0.2.2 doesn't restrict which packets can be onion-routed, which allows a remote attacker to discover a target user's IP address (when knowing only their Tox Id) by positioning themselves close to target's Tox Id in the DHT for the target to establish an onion connection with the attacker, guessing the target's DHT public key and creating a DHT node with public key close to it, and finally onion-routing a NAT Ping Request to the target, requesting it to ping the just created DHT node.

解决建议

建议您更新当前系统或软件至最新版，完成漏洞的修复。
