Bug Description
Upgrading from 1.3.5d to 1.3.5e causes mod_sftp to crash when using ECDSA host keys.
From a fresh install, add the following to the configuration
SFTPEngine on
Port 2222
SFTPHostKey /etc/ssh/
Restart and try to login on port 2222 with sftp. The server will crash during KEX_ECDH.
This used to work with 1.3.5d from 17.10 release.
A workaround for the moment is to only use a RSA key instead, i.e. ssh_host_rsa_key.
From proftpd.log:
".... ProFTPD terminating (signal 11)"
