| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2018-07-26 | CVE-2017-7562 | Improper Certificate Validation vulnerability in multiple products An authentication bypass flaw was found in the way krb5's certauth interface before 1.16.1 handled the validation of client certificates. | 6.5 |
| 2018-03-06 | CVE-2018-5730 | LDAP Injection vulnerability in multiple products MIT krb5 1.6 or later allows an authenticated kadmin with permission to add principals to an LDAP Kerberos database to circumvent a DN containership check by supplying both a "linkdn" and "containerdn" database argument, or by supplying a DN string which is a left extension of a container DN string but is not hierarchically within the container DN. | 3.8 |
| 2018-03-06 | CVE-2018-5729 | NULL Pointer Dereference vulnerability in multiple products MIT krb5 1.6 or later allows an authenticated kadmin with permission to add principals to an LDAP Kerberos database to cause a denial of service (NULL pointer dereference) or bypass a DN container check by supplying tagged data that is internal to the database module. | 4.7 |
| 2017-11-23 | CVE-2017-15088 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in MIT Kerberos 5 plugins/preauth/pkinit/pkinit_crypto_openssl.c in MIT Kerberos 5 (aka krb5) through 1.15.2 mishandles Distinguished Name (DN) fields, which allows remote attackers to execute arbitrary code or cause a denial of service (buffer overflow and application crash) in situations involving untrusted X.509 data, related to the get_matching_data and X509_NAME_oneline_ex functions. | 9.8 |
| 2017-09-13 | CVE-2017-11462 | Double Free vulnerability in multiple products Double free vulnerability in MIT Kerberos 5 (aka krb5) allows attackers to have unspecified impact via vectors involving automatic deletion of security contexts on error. | 9.8 |
| 2017-08-09 | CVE-2017-11368 | Reachable Assertion vulnerability in multiple products In MIT Kerberos 5 (aka krb5) 1.7 and later, an authenticated attacker can cause a KDC assertion failure by sending invalid S4U2Self or S4U2Proxy requests. | 6.5 |
| 2016-08-01 | CVE-2016-3120 | NULL Pointer Dereference vulnerability in MIT Kerberos 5 The validate_as_request function in kdc_util.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before 1.13.6 and 1.4.x before 1.14.3, when restrict_anonymous_to_tgt is enabled, uses an incorrect client data structure, which allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) via an S4U2Self request. | 6.5 |
| 2016-03-26 | CVE-2016-3119 | The process_db_args function in plugins/kdb/ldap/libkdb_ldap/ldap_principal2.c in the LDAP KDB module in kadmind in MIT Kerberos 5 (aka krb5) through 1.13.4 and 1.14.x through 1.14.1 mishandles the DB argument, which allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) via a crafted request to modify a principal. | 5.3 |
| 2016-02-13 | CVE-2015-8631 | Missing Release of Resource after Effective Lifetime vulnerability in multiple products Multiple memory leaks in kadmin/server/server_stubs.c in kadmind in MIT Kerberos 5 (aka krb5) before 1.13.4 and 1.14.x before 1.14.1 allow remote authenticated users to cause a denial of service (memory consumption) via a request specifying a NULL principal name. | 6.5 |
| 2016-02-13 | CVE-2015-8630 | Unspecified vulnerability in MIT Kerberos 5 The (1) kadm5_create_principal_3 and (2) kadm5_modify_principal functions in lib/kadm5/srv/svr_principal.c in kadmind in MIT Kerberos 5 (aka krb5) 1.12.x and 1.13.x before 1.13.4 and 1.14.x before 1.14.1 allow remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) by specifying KADM5_POLICY with a NULL policy name. | 7.5 |
