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").
CVE-2004-0642 3 Debian, Mit, Redhat 5 Debian Linux, Kerberos 5, Enterprise Linux Desktop and 2 more 2025-04-03 7.5 HIGH N/A
Double free vulnerabilities in the error handling code for ASN.1 decoders in the (1) Key Distribution Center (KDC) library and (2) client library for MIT Kerberos 5 (krb5) 1.3.4 and earlier may allow remote attackers to execute arbitrary code.
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-2024-37371 2 Debian, Mit 2 Debian Linux, Kerberos 5 2025-03-13 N/A 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 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-2020-28196 4 Fedoraproject, Mit, Netapp and 1 more 11 Fedora, Kerberos 5, Active Iq Unified Manager and 8 more 2024-11-21 5.0 MEDIUM 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 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-2018-5730 4 Debian, Fedoraproject, Mit and 1 more 6 Debian Linux, Fedora, Kerberos 5 and 3 more 2024-11-21 5.5 MEDIUM 3.8 LOW
MIT krb5 1.6 or later allows an authenticated kadmin with permission to add principals to an LDAP Kerberos database to circumvent a DN containership check by supplying both a "linkdn" and "containerdn" database argument, or by supplying a DN string which is a left extension of a container DN string but is not hierarchically within the container DN.
CVE-2018-5729 4 Debian, Fedoraproject, Mit and 1 more 6 Debian Linux, Fedora, Kerberos 5 and 3 more 2024-11-21 6.5 MEDIUM 4.7 MEDIUM
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.
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.
