| MIT Kerberos V5 Key Distribution Center (KDC) before 1.2.5 allows remote authenticated attackers to cause a denial of service (crash) on KDCs within the same realm via a certain protocol request that causes a null dereference. | |||||

| CVE-2003-0072 | 1 Mit | 2 Kerberos, Kerberos 5 | 2025-04-03 | 5.0 MEDIUM | N/A |
| The Key Distribution Center (KDC) in Kerberos 5 (krb5) 1.2.7 and earlier allows remote, authenticated attackers to cause a denial of service (crash) on KDCs within the same realm using a certain protocol request that causes an out-of-bounds read of an array (aka "array overrun"). | |||||

| Buffer overflows in BSD-based FTP servers allows remote attackers to execute arbitrary commands via a long pattern string containing a {} sequence, as seen in (1) g_opendir, (2) g_lstat, (3) g_stat, and (4) the glob0 buffer as used in the glob functions glob2 and glob3. | |||||
| CVE-2006-3084 | 2 Heimdal, Mit | 2 Heimdal, Kerberos 5 | 2025-04-03 | 7.2 HIGH | N/A |
| The (1) ftpd and (2) ksu programs in (a) MIT Kerberos 5 (krb5) up to 1.5, and 1.4.x before 1.4.4, and (b) Heimdal 0.7.2 and earlier, do not check return codes for setuid calls, which might allow local users to gain privileges by causing setuid to fail to drop privileges. NOTE: as of 20060808, it is not known whether an exploitable attack scenario exists for these issues. | |||||
| 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. | |||||
