| CVE-2024-37371 | Cri | 0.59 | 9.1 | 0.02 | Jun 28, 2024 | In MIT Kerberos 5 (aka krb5) before 1.21.3, an attacker can cause invalid memory reads during GSS message token handling by sending message tokens with invalid length fields. | ||
| CVE-2024-37370 | Hig | 0.49 | 7.5 | 0.01 | Jun 28, 2024 | In MIT Kerberos 5 (aka krb5) before 1.21.3, an attacker can modify the plaintext Extra Count field of a confidential GSS krb5 wrap token, causing the unwrapped token to appear truncated to the application. | ||
| CVE-2025-24528 | Hig | 0.39 | 7.1 | 0.01 | Jan 16, 2026 | In MIT Kerberos 5 (aka krb5) before 1.22 (with incremental propagation), there is an integer overflow for a large update size to resize() in kdb_log.c. An authenticated attacker can cause an out-of-bounds write and kadmind daemon crash. | ||
| CVE-2026-40356 | Med | 0.31 | 5.9 | 0.01 | Apr 28, 2026 | In MIT Kerberos 5 (aka krb5) before 1.22.3, there is an integer underflow and resultant out-of-bounds read if an application calls gss_accept_sec_context() on a system with a NegoEx mechanism registered in /etc/gss/mech. An unauthenticated remote attacker can trigger this,… | ||
| CVE-2026-11850 | Med | 0.26 | 5.0 | 0.00 | Jun 11, 2026 | An integer underflow vulnerability was found in MIT krb5 in the berval2tl_data() function in plugins/kdb/ldap/libkdb_ldap/ldap_principal2.c. The function performs an unsigned subtraction (bv_len - 2) without a prior bounds check. When bv_len is 0 or 1, the subtraction wraps to a… | ||
| CVE-2007-0956 | 0.02 | — | 0.30 | Apr 6, 2007 | 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-2008-0948 | 0.01 | — | 0.07 | Mar 19, 2008 | Buffer overflow in the RPC library (lib/rpc/rpc_dtablesize.c) used by libgssrpc and kadmind in MIT Kerberos 5 (krb5) 1.2.2, and probably other versions before 1.3, when running on systems whose unistd.h does not define the FD_SETSIZE macro, allows remote attackers to cause a… | |||

| CVE-2007-1216 | 0.01 | — | 0.10 | Apr 6, 2007 | 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… | |||
| CVE-2019-14844 | Hig | 0.00 | 7.5 | 0.04 | Sep 26, 2019 | A flaw was found in, Fedora versions of krb5 from 1.16.1 to, including 1.17.x, in the way a Kerberos client could crash the KDC by sending one of the RFC 4556 "enctypes". A remote unauthenticated user could use this flaw to crash the KDC. | ||
| CVE-2018-20217 | Med | 0.00 | 5.3 | 0.01 | Dec 26, 2018 | 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-2017-7562 | Med | 0.00 | 6.5 | 0.03 | Jul 26, 2018 | 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… | ||
| CVE-2018-5730 | Low | 0.00 | 3.8 | 0.02 | Mar 6, 2018 | MIT krb5 1.6 or later allows an authenticated kadmin with permission to add principals to an LDAP Kerberos database to circumvent a DN containership check by supplying both a "linkdn" and "containerdn" database argument, or by supplying a DN string which is a left extension of a… | ||
| CVE-2018-5729 | Med | 0.00 | 4.7 | 0.03 | Mar 6, 2018 | MIT krb5 1.6 or later allows an authenticated kadmin with permission to add principals to an LDAP Kerberos database to cause a denial of service (NULL pointer dereference) or bypass a DN container check by supplying tagged data that is internal to the database module. | ||
| CVE-2010-4022 | 0.00 | — | 0.04 | Feb 10, 2011 | The do_standalone function in the MIT krb5 KDC database propagation daemon (kpropd) in Kerberos 1.7, 1.8, and 1.9, when running in standalone mode, does not properly handle when a worker child process "exits abnormally," which allows remote attackers to cause a denial of service… |
