| 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 | 7.5 HIGH | 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-2022-42898 | 3 Heimdal Project, Mit, Samba | 3 Heimdal, Kerberos 5, Samba | 2025-04-14 | N/A | 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-2015-2697 | 6 Canonical, Debian, Mit and 3 more | 9 Ubuntu Linux, Debian Linux, Kerberos 5 and 6 more | 2025-04-12 | 4.0 MEDIUM | N/A |
| The build_principal_va function in lib/krb5/krb/bld_princ.c in MIT Kerberos 5 (aka krb5) before 1.14 allows remote authenticated users to cause a denial of service (out-of-bounds read and KDC crash) via an initial '\0' character in a long realm field within a TGS request. | |||||
| CVE-2015-2694 | 1 Mit | 1 Kerberos 5 | 2025-04-12 | 5.8 MEDIUM | N/A |
| The kdcpreauth modules in MIT Kerberos 5 (aka krb5) 1.12.x and 1.13.x before 1.13.2 do not properly track whether a client's request has been validated, which allows remote attackers to bypass an intended preauthentication requirement by providing (1) zero bytes of data or (2) an arbitrary realm name, related to plugins/preauth/otp/main.c and plugins/preauth/pkinit/pkinit_srv.c. | |||||
| CVE-2015-2695 | 6 Canonical, Debian, Mit and 3 more | 9 Ubuntu Linux, Debian Linux, Kerberos 5 and 6 more | 2025-04-12 | 5.0 MEDIUM | 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 | 1 Mit | 1 Kerberos 5 | 2025-04-12 | 9.0 HIGH | 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-2014-4341 | 4 Debian, Fedoraproject, Mit and 1 more | 10 Debian Linux, Fedora, Kerberos 5 and 7 more | 2025-04-12 | 5.0 MEDIUM | N/A |
| MIT Kerberos 5 (aka krb5) before 1.12.2 allows remote attackers to cause a denial of service (buffer over-read and application crash) by injecting invalid tokens into a GSSAPI application session. | |||||
| CVE-2015-2698 | 1 Mit | 1 Kerberos 5 | 2025-04-12 | 8.5 HIGH | N/A |
| The iakerb_gss_export_sec_context function in lib/gssapi/krb5/iakerb.c in MIT Kerberos 5 (aka krb5) 1.14 pre-release 2015-09-14 improperly accesses a certain pointer, which allows remote authenticated users to cause a denial of service (memory corruption) or possibly have unspecified other impact by interacting with an application that calls the gss_export_sec_context function. NOTE: this vulnerability exists because of an incorrect fix for CVE-2015-2696. | |||||
| CVE-2015-2696 | 5 Canonical, Debian, Mit and 2 more | 8 Ubuntu Linux, Debian Linux, Kerberos 5 and 5 more | 2025-04-12 | 7.1 HIGH | N/A |
| lib/gssapi/krb5/iakerb.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 IAKERB packet that is mishandled during a gss_inquire_context call. | |||||
| CVE-2014-5353 | 7 Canonical, Debian, Fedoraproject and 4 more | 12 Ubuntu Linux, Debian Linux, Fedora and 9 more | 2025-04-12 | 3.5 LOW | N/A |
| The krb5_ldap_get_password_policy_from_dn function in plugins/kdb/ldap/libkdb_ldap/ldap_pwd_policy.c in MIT Kerberos 5 (aka krb5) before 1.13.1, when the KDC uses LDAP, allows remote authenticated users to cause a denial of service (daemon crash) via a successful LDAP query with no results, as demonstrated by using an incorrect object type for a password policy. | |||||
