Official Description
do_tgs_req.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.11 before 1.11.4, when a single-component realm name is used, allows remote authenticated users to cause a denial of service (daemon crash) via a TGS-REQ request that triggers an attempted cross-realm referral for a host-based service principal.
Technical Analysis
CVE-2013-1417 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
