The config_auth function in ntpd in NTP before 4.2.7p11, when an auth key
is not configured, improperly generates a key, which makes it easier for
remote attackers to defeat cryptographic protection mechanisms via a
brute-force attack.

mdeslaur | upstream commit in 4.2.7p11 removes automatic key generation completely. Red Hat fixed the issue in a different way. |
