| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2023-08-07 | CVE-2023-36054 | Access of Uninitialized Pointer vulnerability in multiple products lib/kadm5/kadm_rpc_xdr.c in MIT Kerberos 5 (aka krb5) before 1.20.2 and 1.21.x before 1.21.1 frees an uninitialized pointer. | 6.5 |
| 2021-08-23 | CVE-2021-37750 | NULL Pointer Dereference vulnerability in multiple products The Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before 1.18.5 and 1.19.x before 1.19.3 has a NULL pointer dereference in kdc/do_tgs_req.c via a FAST inner body that lacks a server field. | 6.5 |
| 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-2018-5729 | 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 |
| 2017-08-09 | 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-2015-8629 | Out-of-bounds Read vulnerability in multiple products The xdr_nullstring function in lib/kadm5/kadm_rpc_xdr.c in kadmind in MIT Kerberos 5 (aka krb5) before 1.13.4 and 1.14.x before 1.14.1 does not verify whether '\0' characters exist as expected, which allows remote authenticated users to obtain sensitive information or cause a denial of service (out-of-bounds read) via a crafted string. | 5.3 |
| 2010-12-02 | CVE-2010-4020 | Cryptographic Issues vulnerability in MIT Kerberos 5 MIT Kerberos 5 (aka krb5) 1.8.x through 1.8.3 does not reject RC4 key-derivation checksums, which might allow remote authenticated users to forge a (1) AD-SIGNEDPATH or (2) AD-KDC-ISSUED signature, and possibly gain privileges, by leveraging the small key space that results from certain one-byte stream-cipher operations. | 6.3 |
