Summary

Panic on crafted authentication request message in golang.org/x/crypto/ssh

Details

Clients can cause a panic in SSH servers. An attacker can craft an authentication request message for the “gssapi-with-mic” method which will cause NewServerConn to panic via a nil pointer dereference if ServerConfig.GSSAPIWithMICConfig is nil.
