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 the KDC to corrupt its heap (aka "buffer underrun").

Buffer overflow in ksu in Kerberos 5 allows local users to gain root privileges.
CVE-2000-0514 1 Mit 1 Kerberos 5 2025-04-03 N/A
GSSFTP FTP daemon in Kerberos 5 1.1.x does not properly restrict access to some FTP commands, which allows remote attackers to cause a denial of service, and local users to gain root privileges.
CVE-2000-0548 3 Cygnus Network Security Project, Kerbnet Project, Mit 4 Cygnus Network Security, Kerbnet, Kerberos and 1 more 2025-04-03 N/A
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.
CVE-2001-0417 1 Mit 2 Kerberos, Kerberos 5 2025-04-03 N/A
Kerberos 4 (aka krb4) allows local users to overwrite arbitrary files via a symlink attack on new ticket files.
CVE-1999-1321 1 Mit 1 Kerberos 2025-04-03 N/A
Buffer overflow in ssh 1.2.26 client with Kerberos V enabled could allow remote attackers to cause a denial of service or execute arbitrary commands via a long DNS hostname that is not properly handled during TGT ticket passing.
CVE-2024-26462 3 Mit, Netapp, Redhat 12 Kerberos 5, Active Iq Unified Manager, Cloud Volumes Ontap Mediator and 9 more 2025-03-25 5.5 Medium
Kerberos 5 (aka krb5) 1.21.2 contains a memory leak vulnerability in /krb5/src/kdc/ndr.c.
CVE-2024-37371 3 Debian, Mit, Redhat 9 Debian Linux, Kerberos 5, Enterprise Linux and 6 more 2025-03-13 9.1 Critical
In MIT Kerberos 5 (aka krb5) before 1.21.3, an attacker can cause invalid memory reads during GSS message token handling by sending message tokens with invalid length fields.
CVE-2024-37370 2 Mit, Redhat 8 Kerberos 5, Enterprise Linux, Rhel Aus and 5 more 2025-03-13 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 2 Mit, Redhat 2 Kerberos 5, Enterprise Linux 2024-11-21 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 4 Debian, Mit, Netapp and 1 more 8 Debian Linux, Kerberos 5, Active Iq Unified Manager and 5 more 2024-11-21 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 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 6 Debian, Fedoraproject, Mit and 3 more 6 Debian Linux, Fedora, Kerberos 5 and 3 more 2024-11-21 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 5 Debian, Mit, Netapp and 2 more 8 Debian Linux, Kerberos 5, Active Iq Unified Manager and 5 more 2024-11-21 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-2020-28196 5 Fedoraproject, Mit, Netapp and 2 more 13 Fedora, Kerberos 5, Active Iq Unified Manager and 10 more 2024-11-21 7.5 High
MIT Kerberos 5 (aka krb5) before 1.17.2 and 1.18.x before 1.18.3 allows unbounded recursion via an ASN.1-encoded Kerberos message because the lib/krb5/asn.1/asn1_encode.c support for BER indefinite lengths lacks a recursion limit.
