| CVE-2000-0549 | 2 Cygnus, Mit | 4 Cygnus Network Security, Kerbnet, Kerberos and 1 more | 2025-04-03 | 5.0 MEDIUM | N/A |
| Kerberos 4 KDC program does not properly check for null termination of AUTH_MSG_KDC_REQUEST requests, which allows remote attackers to cause a denial of service via a malformed request. | |||||
| CVE-2005-1174 | 1 Mit | 1 Kerberos 5 | 2025-04-03 | 5.0 MEDIUM | N/A |
| MIT Kerberos 5 (krb5) 1.3 through 1.4.1 Key Distribution Center (KDC) allows remote attackers to cause a denial of service (application crash) via a certain valid TCP connection that causes a free of unallocated memory. | |||||
| CVE-2024-26462 | 2 Mit, Netapp | 11 Kerberos 5, Active Iq Unified Manager, Cloud Volumes Ontap Mediator and 8 more | 2025-03-25 | N/A | 5.5 MEDIUM |
| Kerberos 5 (aka krb5) 1.21.2 contains a memory leak vulnerability in /krb5/src/kdc/ndr.c. | |||||
| CVE-2024-37370 | 1 Mit | 1 Kerberos 5 | 2025-03-13 | N/A | 7.5 HIGH |
| In MIT Kerberos 5 (aka krb5) before 1.21.3, an attacker can modify the plaintext Extra Count field of a confidential GSS krb5 wrap token, causing the unwrapped token to appear truncated to the application. | |||||
| CVE-2023-39975 | 1 Mit | 1 Kerberos 5 | 2024-11-21 | N/A | 8.8 HIGH |
| kdc/do_tgs_req.c in MIT Kerberos 5 (aka krb5) 1.21 before 1.21.2 has a double free that is reachable if an authenticated user can trigger an authorization-data handling failure. Incorrect data is copied from one ticket to another. | |||||
| CVE-2023-36054 | 3 Debian, Mit, Netapp | 7 Debian Linux, Kerberos 5, Active Iq Unified Manager and 4 more | 2024-11-21 | N/A | 6.5 MEDIUM |
| 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. A remote authenticated user can trigger a kadmind crash. This occurs because _xdr_kadm5_principal_ent_rec does not validate the relationship between n_key_data and the key_data array count. | |||||
| CVE-2022-39028 | 4 Debian, Gnu, Mit and 1 more | 4 Debian Linux, Inetutils, Kerberos 5 and 1 more | 2024-11-21 | N/A | 7.5 HIGH |
| telnetd in GNU Inetutils through 2.3, MIT krb5-appl through 1.0.3, and derivative works has a NULL pointer dereference via 0xff 0xf7 or 0xff 0xf8. In a typical installation, the telnetd application would crash but the telnet service would remain available through inetd. However, if the telnetd application has many crashes within a short time interval, the telnet service would become unavailable after inetd logs a "telnet/tcp server failing (looping), service terminated" error. NOTE: MIT krb5-appl is not supported upstream but is shipped by a few Linux distributions. The affected code was removed from the supported MIT Kerberos 5 (aka krb5) product many years ago, at version 1.8. | |||||
| CVE-2021-37750 | 5 Debian, Fedoraproject, Mit and 2 more | 5 Debian Linux, Fedora, Kerberos 5 and 2 more | 2024-11-21 | 4.0 MEDIUM | 6.5 MEDIUM |
| 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. | |||||
| CVE-2021-36222 | 4 Debian, Mit, Netapp and 1 more | 7 Debian Linux, Kerberos 5, Active Iq Unified Manager and 4 more | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| ec_verify in kdc/kdc_preauth_ec.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before 1.18.4 and 1.19.x before 1.19.2 allows remote attackers to cause a NULL pointer dereference and daemon crash. This occurs because a return value is not properly managed in a certain situation. | |||||
| CVE-2019-14844 | 2 Fedoraproject, Mit | 2 Fedora, Kerberos 5 | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| A flaw was found in, Fedora versions of krb5 from 1.16.1 to, including 1.17.x, in the way a Kerberos client could crash the KDC by sending one of the RFC 4556 "enctypes". A remote unauthenticated user could use this flaw to crash the KDC. | |||||
| CVE-2017-7562 | 2 Mit, Redhat | 5 Kerberos 5, Enterprise Linux, Enterprise Linux Desktop and 2 more | 2024-11-21 | 4.0 MEDIUM | 6.5 MEDIUM |
| An authentication bypass flaw was found in the way krb5's certauth interface before 1.16.1 handled the validation of client certificates. A remote attacker able to communicate with the KDC could potentially use this flaw to impersonate arbitrary principals under rare and erroneous circumstances. | |||||
