The unparse implementation in the Key Distribution Center (KDC) in MIT
Kerberos 5 (aka krb5) 1.6.x through 1.9, when an LDAP backend is used,
allows remote attackers to cause a denial of service (file descriptor
exhaustion and daemon hang) via a principal name that triggers use of a
backslash escape sequence, as demonstrated by a \n sequence.
