Name : krb5
Product : Fedora 29
Version : 1.16.1
Release : 26.fc29

Summary : The Kerberos network authentication system
Description :
Kerberos V5 is a trusted-third-party network authentication system,
which can improve your network's security by eliminating the insecure
practice of sending passwords over the network in unencrypted form.

Update Information:

Fix KDC crash when logging PKINIT enctypes (CVE-2019-14844) This is a purely
denial-of-service issue, though it is unauthenticated, and is unlikely to
trigger by accident.
