Description Petr Menšík 2017-10-31 16:34:34 UTC 
Description of problem:
When named is first started and /etc/rndc.conf or /etc/rndc.key does not exist, /etc/rndc.key is generated. It uses insecure algorithm hmac-md5, when more secure algorithms are supported.

Version-Release number of selected component (if applicable):
bind-9.10.5-2.P2.fc25.x86_64
bind-9.11.1-2.P3.fc26.x86_64

How reproducible:
always

Steps to Reproduce:
1. dnf install bind
2. rm -f /etc/rndc.conf /etc/rndc.key
3. systemctl restart named
4. grep algorithm /etc/rndc.key

Actual results:
$ grep algorithm /etc/rndc.key 
	algorithm hmac-md5;

Expected results:
$ grep algorithm /etc/rndc.key 
	algorithm hmac-sha256;

Additional info:
All supported versions are affected
