CVE-2004-1189 2 Mit, Redhat 2 Kerberos 5, Enterprise Linux 2026-04-16 N/A
The add_to_history function in svr_principal.c in libkadm5srv for MIT Kerberos 5 (krb5) up to 1.3.5, when performing a password change, does not properly track the password policy's history count and the maximum number of keys, which can cause an array index out-of-bounds error and may allow authenticated users to execute arbitrary code via a heap-based buffer overflow.
CVE-2006-3084 2 Heimdal, Mit 2 Heimdal, Kerberos 5 2026-04-16 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-2025-24528 2 Mit, Redhat 5 Kerberos 5, Discovery, Enterprise Linux and 2 more 2026-04-15 7.1 High
In MIT Kerberos 5 (aka krb5) before 1.22 (with incremental propagation), there is an integer overflow for a large update size to resize() in kdb_log.c. An authenticated attacker can cause an out-of-bounds write and kadmind daemon crash.
CVE-2023-39975 2 Mit, Redhat 2 Kerberos 5, Enterprise Linux 2026-02-25 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-2020-28196 5 Fedoraproject, Mit, Netapp and 2 more 13 Fedora, Kerberos 5, Active Iq Unified Manager and 10 more 2025-12-03 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-2024-26458 3 Mit, Netapp, Redhat 13 Kerberos 5, Active Iq Unified Manager, Cloud Volumes Ontap Mediator and 10 more 2025-05-23 5.3 Medium
Kerberos 5 (aka krb5) 1.21.2 contains a memory leak in /krb5/src/lib/rpc/pmap_rmt.c.
CVE-2024-26461 3 Mit, Netapp, Redhat 13 Kerberos 5, Active Iq Unified Manager, Cloud Volumes Ontap Mediator and 10 more 2025-05-23 7.5 High
Kerberos 5 (aka krb5) 1.21.2 contains a memory leak vulnerability in /krb5/src/lib/gssapi/krb5/k5sealv3.c.
CVE-2018-5729 4 Debian, Fedoraproject, Mit and 1 more 7 Debian Linux, Fedora, Kerberos 5 and 4 more 2025-05-05 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-2018-5730 4 Debian, Fedoraproject, Mit and 1 more 7 Debian Linux, Fedora, Kerberos 5 and 4 more 2025-05-05 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-2017-15088 1 Mit 1 Kerberos 5 2025-04-20 9.8 Critical
plugins/preauth/pkinit/pkinit_crypto_openssl.c in MIT Kerberos 5 (aka krb5) through 1.15.2 mishandles Distinguished Name (DN) fields, which allows remote attackers to execute arbitrary code or cause a denial of service (buffer overflow and application crash) in situations involving untrusted X.509 data, related to the get_matching_data and X509_NAME_oneline_ex functions. NOTE: this has security relevance only in use cases outside of the MIT Kerberos distribution, e.g., the use of get_matching_data in KDC certauth plugin code that is specific to Red Hat.
CVE-2017-11368 3 Fedoraproject, Mit, Redhat 4 Fedora, Kerberos, Kerberos 5 and 1 more 2025-04-20 N/A
In MIT Kerberos 5 (aka krb5) 1.7 and later, an authenticated attacker can cause a KDC assertion failure by sending invalid S4U2Self or S4U2Proxy requests.
CVE-2017-11462 2 Fedoraproject, Mit 2 Fedora, Kerberos 5 2025-04-20 N/A
Double free vulnerability in MIT Kerberos 5 (aka krb5) allows attackers to have unspecified impact via vectors involving automatic deletion of security contexts on error.
CVE-2022-42898 4 Heimdal Project, Mit, Redhat and 1 more 10 Heimdal, Kerberos 5, Enterprise Linux and 7 more 2025-04-14 8.8 High
PAC parsing in MIT Kerberos 5 (aka krb5) before 1.19.4 and 1.20.x before 1.20.1 has integer overflows that may lead to remote code execution (in KDC, kadmind, or a GSS or Kerberos application server) on 32-bit platforms (which have a resultant heap-based buffer overflow), and cause a denial of service on other platforms. This occurs in krb5_pac_parse in lib/krb5/krb/pac.c. Heimdal before 7.7.1 has "a similar bug."
CVE-2014-9423 2 Mit, Redhat 2 Kerberos 5, Enterprise Linux 2025-04-12 N/A
The svcauth_gss_accept_sec_context function in lib/rpc/svc_auth_gss.c in MIT Kerberos 5 (aka krb5) 1.11.x through 1.11.5, 1.12.x through 1.12.2, and 1.13.x before 1.13.1 transmits uninitialized interposer data to clients, which allows remote attackers to obtain sensitive information from process heap memory by sniffing the network for data in a handle field.
