23 Nov 2022 — Heimdal before 7.7.1 allows remote attackers to execute arbitrary code because of an invalid free in the ASN.1 codec used by the Key Distribution Center (KDC). Heimdal anterior a 7.7.1 permite a atacantes remotos ejecutar código arbitrario debido a un free no válido en el códec ASN.1 utilizado por el Centro de distribución de claves (KDC). It was discovered that Heimdal incorrectly handled certain SPNEGO tokens. A remote attacker could possibly use this issue to cause a denial of service.

CVSS: 9.0EPSS: 1%CPEs: 7EXPL: 1CVE-2022-42898 – krb5: integer overflow vulnerabilities in PAC parsing
https://notcve.org/view.php?id=CVE-2022-42898
21 Nov 2022 — PAC parsing in MIT Kerberos 5 (aka krb5) before 1.19.4 and 1.20.x before 1.20.1 has integer overflows that may lead to remote code execution (in KDC, kadmind, or a GSS or Kerberos application server) on 32-bit platforms (which have a resultant heap-based buffer overflow), and cause a denial of service on other platforms. This occurs in krb5_pac_parse in lib/krb5/krb/pac.c. Heimdal before 7.7.1 has "a similar bug."

15 Nov 2022 — Heimdal is an implementation of ASN.1/DER, PKIX, and Kerberos. Versions prior to 7.7.1 are vulnerable to a denial of service vulnerability in Heimdal's PKI certificate validation library, affecting the KDC (via PKINIT) and kinit (via PKINIT), as well as any third-party applications using Heimdal's libhx509. Users should upgrade to Heimdal 7.7.1 or 7.8. There are no known workarounds for this issue. Heimdal es una implementación de ASN.1/DER, PKIX y Kerberos. • https://github.com/heimdal/heimdal/security/advisories/GHSA-mgqr-gvh6-23cx • CWE-193: Off-by-one Error •

17 Oct 2022 — The Heimdal Software Kerberos 5 implementation is vulnerable to a null pointer dereferance.

15 May 2019 — In the client side of Heimdal before 7.6.0, failure to verify anonymous PKINIT PA-PKINIT-KX key exchange permits a man-in-the-middle attack. This issue is in krb5_init_creds_step in lib/krb5/init_creds_pw.c.

06 Dec 2017 — In Heimdal through 7.4, remote unauthenticated attackers are able to crash the KDC by sending a crafted UDP packet containing empty data fields for client name or realm. The parser would unconditionally dereference NULL pointers in that case, leading to a segmentation fault. This is related to the _kdc_as_rep function in kdc/kerberos5.c and the der_length_visible_string function in lib/asn1/der_length.c.

28 Aug 2017 — The transit path validation code in Heimdal before 7.3 might allow attackers to bypass the capath policy protection mechanism by leveraging failure to add the previous hop realm to the transit path of issued tickets. El código de validación de ruta de tránsito en Heimdal en versiones anteriores a la 7.3 podría permitir que atacantes omitan el mecanismo de protección de política capath aprovechándose del error a la hora de añadir el dominio de salto anterior a la ruta de tránsito de tickets emitidos. • http://lists.opensuse.org/opensuse-updates/2017-08/msg00062.html • CWE-295: Improper Certificate Validation •

13 Jul 2017 — Heimdal before 7.4 allows remote attackers to impersonate services with Orpheus' Lyre attacks because it obtains service-principal names in a way that violates the Kerberos 5 protocol specification. In _krb5_extract_ticket() the KDC-REP service name must be obtained from the encrypted version stored in 'enc_part' instead of the unencrypted version stored in 'ticket'. Use of the unencrypted version provides an opportunity for successful server impersonation and other attacks.
