Detail

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.

Id Description
70908 Kerberos KDC LDAP Backend Unparse Implementation DoS

Kerberos contains a flaw that may allow a remote denial of service. The issue is triggered when the unparse implementation in the Key Distribution Center improperly processes certain principal names which trigger backslash escape sequences, when an LDAP backend is used, allowing a remote attacker to cause a denial of service via a crafted request.
