| 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-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-2017-11462 | 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-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 |

| 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-2014-9421 | 2 Mit, Redhat | 2 Kerberos 5, Enterprise Linux | 2025-04-12 | N/A |
| The auth_gssapi_unwrap_data function in lib/rpc/auth_gssapi_misc.c in MIT Kerberos 5 (aka krb5) through 1.11.5, 1.12.x through 1.12.2, and 1.13.x before 1.13.1 does not properly handle partial XDR deserialization, which allows remote authenticated users to cause a denial of service (use-after-free and double free, and daemon crash) or possibly execute arbitrary code via malformed XDR data, as demonstrated by data sent to kadmind. | ||||
| CVE-2015-2695 | 6 Canonical, Debian, Mit and 3 more | 9 Ubuntu Linux, Debian Linux, Kerberos 5 and 6 more | 2025-04-12 | N/A |
| lib/gssapi/spnego/spnego_mech.c in MIT Kerberos 5 (aka krb5) before 1.14 relies on an inappropriate context handle, which allows remote attackers to cause a denial of service (incorrect pointer read and process crash) via a crafted SPNEGO packet that is mishandled during a gss_inquire_context call. | ||||
| CVE-2014-5352 | 2 Mit, Redhat | 2 Kerberos 5, Enterprise Linux | 2025-04-12 | N/A |
| The krb5_gss_process_context_token function in lib/gssapi/krb5/process_context_token.c in the libgssapi_krb5 library in MIT Kerberos 5 (aka krb5) through 1.11.5, 1.12.x through 1.12.2, and 1.13.x before 1.13.1 does not properly maintain security-context handles, which allows remote authenticated users to cause a denial of service (use-after-free and double free, and daemon crash) or possibly execute arbitrary code via crafted GSSAPI traffic, as demonstrated by traffic to kadmind. | ||||
| CVE-2014-5354 | 1 Mit | 2 Kerberos, Kerberos 5 | 2025-04-12 | N/A |
| plugins/kdb/ldap/libkdb_ldap/ldap_principal2.c in MIT Kerberos 5 (aka krb5) 1.12.x and 1.13.x before 1.13.1, when the KDC uses LDAP, allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) by creating a database entry for a keyless principal, as demonstrated by a kadmin "add_principal -nokey" or "purgekeys -all" command. | ||||
| CVE-2014-9422 | 2 Mit, Redhat | 2 Kerberos 5, Enterprise Linux | 2025-04-12 | N/A |
| The check_rpcsec_auth function in kadmin/server/kadm_rpc_svc.c in kadmind in MIT Kerberos 5 (aka krb5) through 1.11.5, 1.12.x through 1.12.2, and 1.13.x before 1.13.1 allows remote authenticated users to bypass a kadmin/* authorization check and obtain administrative access by leveraging access to a two-component principal with an initial "kadmind" substring, as demonstrated by a "ka/x" principal. | ||||
| CVE-2014-4342 | 3 Debian, Mit, Redhat | 8 Debian Linux, Kerberos, Kerberos 5 and 5 more | 2025-04-12 | N/A |
| MIT Kerberos 5 (aka krb5) 1.7.x through 1.12.x before 1.12.2 allows remote attackers to cause a denial of service (buffer over-read or NULL pointer dereference, and application crash) by injecting invalid tokens into a GSSAPI application session. | ||||
| CVE-2014-4344 | 3 Debian, Mit, Redhat | 7 Debian Linux, Kerberos 5, Enterprise Linux and 4 more | 2025-04-12 | N/A |
| The acc_ctx_cont function in the SPNEGO acceptor in lib/gssapi/spnego/spnego_mech.c in MIT Kerberos 5 (aka krb5) 1.5.x through 1.12.x before 1.12.2 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via an empty continuation token at a certain point during a SPNEGO negotiation. | ||||
| CVE-2015-8630 | 2 Mit, Redhat | 2 Kerberos 5, Enterprise Linux | 2025-04-12 | N/A |
| The (1) kadm5_create_principal_3 and (2) kadm5_modify_principal functions in lib/kadm5/srv/svr_principal.c in kadmind in MIT Kerberos 5 (aka krb5) 1.12.x and 1.13.x before 1.13.4 and 1.14.x before 1.14.1 allow remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) by specifying KADM5_POLICY with a NULL policy name. | ||||
| 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. | ||||
| CVE-2014-5355 | 2 Mit, Redhat | 2 Kerberos 5, Enterprise Linux | 2025-04-12 | N/A |
| MIT Kerberos 5 (aka krb5) through 1.13.1 incorrectly expects that a krb5_read_message data field is represented as a string ending with a '\0' character, which allows remote attackers to (1) cause a denial of service (NULL pointer dereference) via a zero-byte version string or (2) cause a denial of service (out-of-bounds read) by omitting the '\0' character, related to appl/user_user/server.c and lib/krb5/krb/recvauth.c. | ||||
