  Date Alert Description
5.3 2018-12-26 CVE-2018-20217

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.

6.5 2018-01-16 CVE-2018-5710

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.

7.5 2018-01-16 CVE-2018-5709

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.

9.8 2017-11-23 CVE-2017-15088

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.

6.5 2016-02-12 CVE-2015-8631

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.

3.1 2016-02-12 CVE-2015-8629

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.

6.8 2015-11-08 CVE-2015-2697

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.

7.1 2015-11-08 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.

7.1 2015-11-08 CVE-2015-2695

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.

3.5 2014-12-16 CVE-2014-5353

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.

5 2014-07-20 CVE-2014-4342

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.

5 2014-07-20 CVE-2014-4341

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.

4 2013-11-17 CVE-2013-6800

An unspecified third-party database module for the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.10.x allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) via a crafted request, a different vulnerability than CVE-2013-1418.

4.3 2013-11-17 CVE-2013-1418

The setup_server_realm function in main.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before 1.10.7, when multiple realms are configured, allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a crafted request.

5 2013-05-29 CVE-2002-2443

schpw.c in the kpasswd service in kadmind in MIT Kerberos 5 (aka krb5) before 1.11.3 does not properly validate UDP packets before sending responses, which allows remote attackers to cause a denial of service (CPU and bandwidth consumption) via a forged packet that triggers a communication loop, as demonstrated by krb_pingpong.nasl, a related issue to CVE-1999-0103.
