CVE-2018-5709 [HIGH] CWE-190 CVE-2018-5709: An issue was discovered in MIT Kerberos 5 (aka krb5) through 1.16. There is a variable "dbentry->n_k 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.

CVE-2015-3206 [CRITICAL] CWE-287 python-kerberos vulnerable to KDC spoofing attacks python-kerberos vulnerable to KDC spoofing attacks The `checkPassword` function in python-kerberos does not authenticate the KDC it attempts to communicate with, which allows remote attackers to cause a denial of service (bad response), or have other unspecified impact by performing a man-in-the-middle attack.

CVE-2020-13110 [HIGH] CWE-427 DLL Injection in kerberos DLL Injection in kerberos Version of `kerberos` prior to 1.0.0 are vulnerable to DLL Injection. The package loads DLLs without specifying a full path. This may allow attackers to create a file with the same name in a folder that precedes the intended file in the DLL path search. Doing so would allow attackers to execute arbitrary code in the machine. ## Recommendation Upgrade to version 1.0.0 or later.

CVE-2017-11368 [MEDIUM] CWE-617 CVE-2017-11368: In MIT Kerberos 5 (aka krb5) 1.7 and later, an authenticated attacker can cause a KDC assertion fail 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-2010-0283 [HIGH] CWE-20 CVE-2010-0283: The Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.7 before 1.7.2, and 1.8 alpha, allo The Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.7 before 1.7.2, and 1.8 alpha, allows remote attackers to cause a denial of service (assertion failure and daemon crash) via an invalid (1) AS-REQ or (2) TGS-REQ request.

CVE-2018-5710 [MEDIUM] CWE-476 CVE-2018-5710: An issue was discovered in MIT Kerberos 5 (aka krb5) through 1.16. The pre-defined function "strlen" 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 kadmi

CVE-2003-0138 [HIGH] CVE-2003-0138: Version 4 of the Kerberos protocol (krb4), as used in Heimdal and other packages, allows an attacker Version 4 of the Kerberos protocol (krb4), as used in Heimdal and other packages, allows an attacker to impersonate any principal in a realm via a chosen-plaintext attack.

CVE-2003-0139 [HIGH] CVE-2003-0139: Certain weaknesses in the implementation of version 4 of the Kerberos protocol (krb4) in the krb5 di Certain weaknesses in the implementation of version 4 of the Kerberos protocol (krb4) in the krb5 distribution, when triple-DES keys are used to key krb4 services, allow an attacker to create krb4 tickets for unauthorized principals using a cut-and-paste attack and "ticket splicing."

CVE-2018-20217 [MEDIUM] CWE-617 CVE-2018-20217: A Reachable Assertion issue was discovered in the KDC in MIT Kerberos 5 (aka krb5) before 1.17. If a 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.

CVE-2009-0845 [MEDIUM] CWE-20 CVE-2009-0845: The spnego_gss_accept_sec_context function in lib/gssapi/spnego/spnego_mech.c in MIT Kerberos 5 (aka The spnego_gss_accept_sec_context function in lib/gssapi/spnego/spnego_mech.c in MIT Kerberos 5 (aka krb5) 1.5 through 1.6.3, when SPNEGO is used, allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via invalid ContextFlags data in the reqFlags field in a negTokenInit token.

CVE-1999-1321 [HIGH] CVE-1999-1321: Buffer overflow in ssh 1.2.26 client with Kerberos V enabled could allow remote attackers to cause a Buffer overflow in ssh 1.2.26 client with Kerberos V enabled could allow remote attackers to cause a denial of service or execute arbitrary commands via a long DNS hostname that is not properly handled during TGT ticket passing.

CVE-2014-4342 [MEDIUM] CWE-119 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 deni 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-2009-0844 [MEDIUM] CWE-119 CVE-2009-0844: The get_input_token function in the SPNEGO implementation in MIT Kerberos 5 (aka krb5) 1.5 through 1 The get_input_token function in the SPNEGO implementation in MIT Kerberos 5 (aka krb5) 1.5 through 1.6.3 allows remote attackers to cause a denial of service (daemon crash) and possibly obtain sensitive information via a crafted length value that triggers a buffer over-read.

CVE-2000-0392 [HIGH] CVE-2000-0392: Buffer overflow in ksu in Kerberos 5 allows local users to gain root privileges. Buffer overflow in ksu in Kerberos 5 allows local users to gain root privileges.
