| Buffer overflow in Kerberos 4 KDC program allows remote attackers to cause a denial of service via the e_msg variable in the kerb_err_reply function. | |||||
| CVE-2003-0082 | 1 Mit | 2 Kerberos, Kerberos 5 | 2026-04-16 | 5.0 MEDIUM | N/A |
| The Key Distribution Center (KDC) in Kerberos 5 (krb5) 1.2.7 and earlier allows remote, authenticated attackers to cause a denial of service (crash) on KDCs within the same realm using a certain protocol request that causes the KDC to corrupt its heap (aka "buffer underrun"). | |||||
| CVE-2017-11368 | 2 Fedoraproject, Mit | 3 Fedora, Kerberos, Kerberos 5 | 2025-04-20 | 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-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-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-2018-5710 | 1 Mit | 1 Kerberos | 2024-11-21 | 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-2018-5709 | 1 Mit | 1 Kerberos | 2024-11-21 | 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-2018-20217 | 2 Debian, Mit | 2 Debian Linux, Kerberos | 2024-11-21 | 3.5 LOW | 5.3 MEDIUM |
| A Reachable Assertion issue was discovered in the KDC in MIT Kerberos 5 (aka krb5) before 1.17. If an attacker can obtain a krbtgt ticket using an older encryption type (single-DES, triple-DES, or RC4), the attacker can crash the KDC by making an S4U2Self request. | |||||
