MIT Kerberos 5 1.6.x-1.9 - Denial of Service via LDAP Backend Principal Name Backslash Escape

Title source: llm
STIX 2.1

Description

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.
