Description Adam Mariš 2017-07-14 08:52:59 EDT
Knot DNS before 2.4.5 and 2.5.x before 2.5.2 contains a flaw within the
TSIG protocol implementation that would allow an attacker with a valid
key name and algorithm to bypass TSIG authentication if no additional
ACL restrictions are set, because of an improper TSIG validity period
