Summary

apache-sshd security update

Details

Apache SSHD is a 100% pure java library to support the SSH protocols on both the client and server side.

Security Fix(es):

Class org.apache.sshd.server.keyprovider.SimpleGeneratorHostKeyProvider in Apache MINA SSHD <= 2.9.1 uses Java deserialization to load a serialized java.security.PrivateKey. The class is one of several implementations that an implementor using Apache MINA SSHD can choose for loading the host keys of an SSH server.(CVE-2022-45047)

Severity

9.8 (Critical)
