CVE-2006-3083 3 Heimdal, Mit, Redhat 3 Heimdal, Kerberos 5, Enterprise Linux 2025-04-03 N/A
The (1) krshd and (2) v4rcp applications in (a) MIT Kerberos 5 (krb5) up to 1.5, and 1.4.x before 1.4.4, when running on Linux and AIX, and (b) Heimdal 0.7.2 and earlier, do not check return codes for setuid calls, which allows local users to gain privileges by causing setuid to fail to drop privileges using attacks such as resource exhaustion.
CVE-2006-3084 2 Heimdal, Mit 2 Heimdal, Kerberos 5 2025-04-03 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-2000-0389 3 Cygnus, Mit, Redhat 5 Cygnus Network Security, Kerbnet, Kerberos and 2 more 2025-04-03 N/A
Buffer overflow in krb_rd_req function in Kerberos 4 and 5 allows remote attackers to gain root privileges.
CVE-2000-0549 2 Cygnus, Mit 4 Cygnus Network Security, Kerbnet, Kerberos and 1 more 2025-04-03 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-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-1999-0143 3 Mit, Process Software, Sun 4 Kerberos, Kerberos 5, Multinet and 1 more 2025-04-03 N/A
Kerberos 4 key servers allow a user to masquerade as another by breaking and generating session keys.
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.
CVE-2019-14844 2 Fedoraproject, Mit 2 Fedora, Kerberos 5 2024-11-21 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 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.
