A malicious server can redirect the Commons Net code to use a different host, but the user has to connect to the malicious server in the first place. This may lead to leakage of information about services running on the private network of the client.

For the stable distribution (bullseye), this problem has been fixed in version 3.6-1+deb11u1.

We recommend that you upgrade your libcommons-net-java packages.

For the detailed security status of libcommons-net-java please refer to its security tracker page at: [link moved to references]");
