CVE-2017-7562 | 2 Mit, Redhat | 5 Kerberos 5, Enterprise Linux, Enterprise Linux Desktop and 2 more | 2024-02-28 | 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. | |||||
CVE-2017-11462 | 2 Fedoraproject, Mit | 2 Fedora, Kerberos 5 | 2024-02-28 | 7.5 HIGH | 9.8 CRITICAL |
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-2017-11368 | 2 Fedoraproject, Mit | 3 Fedora, Kerberos, Kerberos 5 | 2024-02-28 | 4.0 MEDIUM | 6.5 MEDIUM |
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-2018-5709 | 1 Mit | 1 Kerberos | 2024-02-28 | 5.0 MEDIUM | 7.5 HIGH |
An issue was discovered in MIT Kerberos 5 (aka krb5) through 1.16. There is a variable "dbentry->n_key_data" in kadmin/dbutil/dump.c that can store 16-bit data but unknowingly the developer has assigned a "u4" variable to it, which is for 32-bit data. An attacker can use this vulnerability to affect other artifacts of the database as we know that a Kerberos database dump file contains trusted data. | |||||
CVE-2017-15088 | 1 Mit | 1 Kerberos 5 | 2024-02-28 | 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-2018-5710 | 1 Mit | 1 Kerberos | 2024-02-28 | 4.0 MEDIUM | 6.5 MEDIUM |
An issue was discovered in MIT Kerberos 5 (aka krb5) through 1.16. The pre-defined function "strlen" is getting a "NULL" string as a parameter value in plugins/kdb/ldap/libkdb_ldap/ldap_principal2.c in the Key Distribution Center (KDC), which allows remote authenticated users to cause a denial of service (NULL pointer dereference) via a modified kadmin client. | |||||
CVE-2016-3120 | 1 Mit | 1 Kerberos 5 | 2024-02-28 | 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-2015-2698 | 1 Mit | 1 Kerberos 5 | 2024-02-28 | 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. | |||||

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-2015-8629 | 5 Debian, Mit, Opensuse and 2 more | 12 Debian Linux, Kerberos 5, Leap and 9 more | 2024-02-28 | 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-2016-3119 | 2 Mit, Opensuse | 3 Kerberos 5, Leap, Opensuse | 2024-02-28 | 3.5 LOW | 5.3 MEDIUM |

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. | |||||
