CVE-2018-20217 |
A Reachable Assertion issue was discovered in the KDC in MIT Kerberos 5 (aka krb5) before 1.17. If an attacker can obtain a krbtgt ticket using an older encryption type (single-DES, triple-DES, or RC4), the attacker can crash the KDC by making an S4U2Self request.

V3.1: 5.3 MEDIUM V2.0: 3.5 LOW |
CVE-2018-5710 |
An issue was discovered in MIT Kerberos 5 (aka krb5) through 1.16. The pre-defined function "strlen" is getting a "NULL" string as a parameter value in plugins/kdb/ldap/libkdb_ldap/ldap_principal2.c in the Key Distribution Center (KDC), which allows remote authenticated users to cause a denial of service (NULL pointer dereference) via a modified kadmin client.

V3.0: 6.5 MEDIUM V2.0: 4.0 MEDIUM |
CVE-2018-5709 |
An issue was discovered in MIT Kerberos 5 (aka krb5) through 1.16. There is a variable "dbentry->n_key_data" in kadmin/dbutil/dump.c that can store 16-bit data but unknowingly the developer has assigned a "u4" variable to it, which is for 32-bit data. An attacker can use this vulnerability to affect other artifacts of the database as we know that a Kerberos database dump file contains trusted data. Published: January 16, 2018; 4:29:00 AM -0500 |
V3.0: 7.5 HIGH V2.0: 5.0 MEDIUM |
CVE-2003-0138 |
Version 4 of the Kerberos protocol (krb4), as used in Heimdal and other packages, allows an attacker to impersonate any principal in a realm via a chosen-plaintext attack. Published: March 24, 2003; 12:00:00 AM -0500 |
V3.x:(not available) V2.0: 7.5 HIGH |
CVE-2003-0139 |
Certain weaknesses in the implementation of version 4 of the Kerberos protocol (krb4) in the krb5 distribution, when triple-DES keys are used to key krb4 services, allow an attacker to create krb4 tickets for unauthorized principals using a cut-and-paste attack and "ticket splicing."

V3.x:(not available) V2.0: 7.5 HIGH |
CVE-2001-0417 |
Kerberos 4 (aka krb4) allows local users to overwrite arbitrary files via a symlink attack on new ticket files. Published: June 27, 2001; 12:00:00 AM -0400 |
V3.x:(not available) V2.0: 2.1 LOW |
CVE-2000-0546 |
Buffer overflow in Kerberos 4 KDC program allows remote attackers to cause a denial of service via the lastrealm variable in the set_tgtkey function. Published: June 09, 2000; 12:00:00 AM -0400 |
V3.x:(not available) V2.0: 5.0 MEDIUM |
CVE-2000-0547 |
Buffer overflow in Kerberos 4 KDC program allows remote attackers to cause a denial of service via the localrealm variable in the process_v4 function. Published: June 09, 2000; 12:00:00 AM -0400 |
V3.x:(not available) V2.0: 5.0 MEDIUM |
CVE-2000-0548 |
Buffer overflow in Kerberos 4 KDC program allows remote attackers to cause a denial of service via the e_msg variable in the kerb_err_reply function. Published: June 09, 2000; 12:00:00 AM -0400 |
