| 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-2014-4342 | 3 Debian, Mit, Redhat | 7 Debian Linux, Kerberos, Kerberos 5 and 4 more | 2025-04-12 | 5.0 MEDIUM | 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-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-2015-8629 | 5 Debian, Mit, Opensuse and 2 more | 12 Debian Linux, Kerberos 5, Leap and 9 more | 2025-04-12 | 2.1 LOW | 5.3 MEDIUM |
| The xdr_nullstring function in lib/kadm5/kadm_rpc_xdr.c in kadmind in MIT Kerberos 5 (aka krb5) before 1.13.4 and 1.14.x before 1.14.1 does not verify whether '\0' characters exist as expected, which allows remote authenticated users to obtain sensitive information or cause a denial of service (out-of-bounds read) via a crafted string. | |||||
| CVE-2014-4343 | 3 Debian, Mit, Redhat | 6 Debian Linux, Kerberos 5, Enterprise Linux Desktop and 3 more | 2025-04-12 | 7.6 HIGH | N/A |
| Double free vulnerability in the init_ctx_reselect function in the SPNEGO initiator in lib/gssapi/spnego/spnego_mech.c in MIT Kerberos 5 (aka krb5) 1.10.x through 1.12.x before 1.12.2 allows remote attackers to cause a denial of service (memory corruption) or possibly execute arbitrary code via network traffic that appears to come from an intended acceptor, but specifies a security mechanism different from the one proposed by the initiator. | |||||
| CVE-2016-3120 | 1 Mit | 1 Kerberos 5 | 2025-04-12 | 4.0 MEDIUM | 6.5 MEDIUM |
| The validate_as_request function in kdc_util.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before 1.13.6 and 1.4.x before 1.14.3, when restrict_anonymous_to_tgt is enabled, uses an incorrect client data structure, which allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) via an S4U2Self request. | |||||
| 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-2015-8631 | 5 Debian, Mit, Opensuse and 2 more | 11 Debian Linux, Kerberos 5, Leap and 8 more | 2025-04-12 | 4.0 MEDIUM | 6.5 MEDIUM |
| Multiple memory leaks in kadmin/server/server_stubs.c in kadmind in MIT Kerberos 5 (aka krb5) before 1.13.4 and 1.14.x before 1.14.1 allow remote authenticated users to cause a denial of service (memory consumption) via a request specifying a NULL principal name. | |||||
| CVE-2014-9421 | 1 Mit | 1 Kerberos 5 | 2025-04-12 | 9.0 HIGH | N/A |

| CVE-2014-5354 | 1 Mit | 2 Kerberos, Kerberos 5 | 2025-04-12 | 3.5 LOW | 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-2014-4341 | 4 Debian, Fedoraproject, Mit and 1 more | 10 Debian Linux, Fedora, Kerberos 5 and 7 more | 2025-04-12 | 5.0 MEDIUM | N/A |
