CVE-2013-1416
Fixed in a distro release EPSS 3%
The prep_reprocess_req function in do_tgs_req.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before 1.10.5 does not properly perform service-principal realm referral, which allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) via a crafted TGS-REQ request.
Products: mit kerberos_5, opensuse, fedoraproject fedora, redhat enterprise_linux_desktop, redhat enterprise_linux_eus, redhat enterprise_linux_server, redhat enterprise_linux_server_aus, redhat enterprise_linux_workstation
