shadowsocks-libev — security advisory
An exploitable information disclosure vulnerability exists in the network packet handling functionality of Shadowsocks-libev 3.3.2. When utilizing a Stream Cipher, a specially crafted set of network packets can cause an outbound connection from the server, resulting in information disclosure. An attacker can send arbitrary packets to trigger this vulnerability.
