CVE-2026-58216
An out-of-bounds read flaw was found in Samba's Kerberos Key Distribution Center's KDC password change kpasswd service. When processing malformed ASN.1-encoded Kerberos password change request, Samba server miscalculates the structure size and attempts to read up to six bytes beyond the end of th...
Unity Linux 20.1060e / 20.1070e Security Update: krb5 (UTSA-2026-017424)
The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-017424 advisory. The Key Distribution Center KDC in MIT Kerberos 5 aka krb5 before 1.18.5 and 1.19.x before 1.19.3 has a NULL pointer dereference in kdc/dotgsreq.c via a FAST inner...
The vulnerability of the kdc/do_tgs_req.c component of the Kerberos authentication protocol allows a attacker to induce a service failure.
The vulnerability of the kdc/dotgsreq.c component of the Kerberos authentication protocol is related to pointer arithmetic errors. Exploiting this vulnerability could allow a malicious actor to cause service interruptions...

The remote MiracleLinux 4 host has packages installed that are affected by a vulnerability as referenced in the AXSA:2013-413:02 advisory. Kerberos V5 is a trusted-third-party network authentication system, which can improve your network's security by eliminating the insecure practice of sending...
[SECURITY] Fedora 42 Update: python-kdcproxy-1.1.0-1.fc42
This package contains a Python WSGI module for proxying KDC requests over HTTP by following the MS-KKDCP protocol. It aims to be simple to deploy, with minimal configuration...
python-kdcproxy: Remote DoS via unbounded TCP upstream buffering
If an attacker causes kdcproxy to connect to an attacker-controlled KDC server e.g. through server-side request forgery, they can exploit the fact that kdcproxy does not enforce bounds on TCP response length to conduct a denial-of-service attack. While receiving the KDC's response, kdcproxy copie...
python-kdcproxy: Unauthenticated SSRF via Realm‑Controlled DNS SRV
If kdcproxy receives a request for a realm which does not have server addresses defined in its configuration, by default, it will query SRV records in the DNS zone matching the requested realm name. This creates a server-side request forgery vulnerability, since an attacker could send a request f...

Siemens SIMATIC S7-1500 NULL Pointer Dereference (CVE-2021-36222)
ecverify in kdc/kdcpreauthec.c in the Key Distribution Center KDC in MIT Kerberos 5 aka krb5 before 1.18.4 and 1.19.x before 1.19.2 allows remote attackers to cause a NULL pointer dereference and daemon crash. This occurs because a return value is not properly managed in a certain situation. This...

CVE-2025-59089
CVE-2025-59089 is a DoS in python-kdcproxy caused by unbounded TCP buffering and permissive handling of response chunks, enabling memory/CPU exhaustion when kdcproxy connects to attacker-controlled KDCs. Related issue CVE-2025-59088 concerns SSRF via DNS SRV discovery for realms, allowing probing...
