CVE-2010-1321 7 Canonical, Debian, Fedoraproject and 4 more 7 Ubuntu Linux, Debian Linux, Fedora and 4 more 2021-02-02 6.8 MEDIUM N/A
The kg_accept_krb5 function in krb5/accept_sec_context.c in the GSS-API library in MIT Kerberos 5 (aka krb5) through 1.7.1 and 1.8 before 1.8.2, as used in kadmind and other applications, does not properly check for invalid GSS-API tokens, which allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) via an AP-REQ message in which the authenticator's checksum field is missing.
CVE-2015-2696 5 Canonical, Debian, Mit and 2 more 8 Ubuntu Linux, Debian Linux, Kerberos 5 and 5 more 2021-02-02 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-2002-2443 6 Canonical, Debian, Fedoraproject and 3 more 10 Ubuntu Linux, Debian Linux, Fedora and 7 more 2021-02-02 5.0 MEDIUM N/A
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.
CVE-2013-1416 4 Fedoraproject, Mit, Opensuse and 1 more 8 Fedora, Kerberos 5, Opensuse and 5 more 2021-02-02 4.0 MEDIUM N/A
The prep_reprocess_req function in do_tgs_req.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before 1.10.5 does not properly perform service-principal realm referral, which allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) via a crafted TGS-REQ request.

The pkinit_check_kdc_pkid function in plugins/preauth/pkinit/pkinit_crypto_openssl.c in the PKINIT implementation in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before 1.10.4 and 1.11.x before 1.11.1 does not properly handle errors during extraction of fields from an X.509 certificate, which allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a malformed KRB5_PADATA_PK_AS_REQ AS-REQ request.
CVE-2012-1016 1 Mit 1 Kerberos 5 2021-02-02 5.0 MEDIUM N/A
The pkinit_server_return_padata function in plugins/preauth/pkinit/pkinit_srv.c in the PKINIT implementation in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before 1.10.4 attempts to find an agility KDF identifier in inappropriate circumstances, which allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a crafted Draft 9 request.
CVE-2007-2798 3 Canonical, Debian, Mit 3 Ubuntu Linux, Debian Linux, Kerberos 5 2021-02-02 9.0 HIGH N/A
Stack-based buffer overflow in the rename_principal_2_svc function in kadmind for MIT Kerberos 1.5.3, 1.6.1, and other versions allows remote authenticated users to execute arbitrary code via a crafted request to rename a principal.
CVE-2007-2442 3 Canonical, Debian, Mit 3 Ubuntu Linux, Debian Linux, Kerberos 5 2021-02-02 10.0 HIGH N/A
The gssrpc__svcauth_gssapi function in the RPC library in MIT Kerberos 5 (krb5) 1.6.1 and earlier might allow remote attackers to execute arbitrary code via a zero-length RPC credential, which causes kadmind to free an uninitialized pointer during cleanup.
CVE-2007-2443 3 Canonical, Debian, Mit 3 Ubuntu Linux, Debian Linux, Kerberos 5 2021-02-02 8.3 HIGH N/A
Integer signedness error in the gssrpc__svcauth_unix function in svc_auth_unix.c in the RPC library in MIT Kerberos 5 (krb5) 1.6.1 and earlier might allow remote attackers to execute arbitrary code via a negative length value.
CVE-2007-0957 3 Canonical, Debian, Mit 3 Ubuntu Linux, Debian Linux, Kerberos 5 2021-02-02 9.0 HIGH N/A
Stack-based buffer overflow in the krb5_klog_syslog function in the kadm5 library, as used by the Kerberos administration daemon (kadmind) and Key Distribution Center (KDC), in MIT krb5 before 1.6.1 allows remote authenticated users to execute arbitrary code and modify the Kerberos key database via crafted arguments, possibly involving certain format string specifiers.
CVE-2007-0956 3 Canonical, Debian, Mit 3 Ubuntu Linux, Debian Linux, Kerberos 5 2021-02-02 10.0 HIGH N/A
The telnet daemon (telnetd) in MIT krb5 before 1.6.1 allows remote attackers to bypass authentication and gain system access via a username beginning with a '-' character, a similar issue to CVE-2007-0882.
CVE-2007-1216 3 Canonical, Debian, Mit 3 Ubuntu Linux, Debian Linux, Kerberos 5 2021-02-02 9.0 HIGH N/A
Double free vulnerability in the GSS-API library (lib/gssapi/krb5/k5unseal.c), as used by the Kerberos administration daemon (kadmind) in MIT krb5 before 1.6.1, when used with the authentication method provided by the RPCSEC_GSS RPC library, allows remote authenticated users to execute arbitrary code and modify the Kerberos key database via a message with an "an invalid direction encoding".
CVE-2004-1189 1 Mit 1 Kerberos 5 2021-02-02 7.2 HIGH N/A
The add_to_history function in svr_principal.c in libkadm5srv for MIT Kerberos 5 (krb5) up to 1.3.5, when performing a password change, does not properly track the password policy's history count and the maximum number of keys, which can cause an array index out-of-bounds error and may allow authenticated users to execute arbitrary code via a heap-based buffer overflow.
CVE-2006-6144 1 Mit 1 Kerberos 5 2021-02-02 5.0 MEDIUM N/A
The "mechglue" abstraction interface of the GSS-API library for Kerberos 5 1.5 through 1.5.1, as used in Kerberos administration daemon (kadmind) and other products that use this library, allows remote attackers to cause a denial of service (crash) via unspecified vectors that cause mechglue to free uninitialized pointers.

CVE-2017-15088 1 Mit 1 Kerberos 5 2021-01-26 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.
