Package: vsftpd
Version: 3.0.3-12
Description:
When an authentication is blocked by PAM (module: pam_abl.so) because of
the remote-host is blocked the vsftpd service is stalled and doesn't accept
connection until service is restarted (reload is not enough).
I guess vsftpd have a bug when it gets the communication.
This doesn't happen when an authentication is rejected because of the user
is blocked (I assume vsftpd understand the communication is this case).
I assume it's related to the bug submit:
