Descriptions
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.
La función pkinit_check_kdc_pkid en plugins / PREAUTH / pkinit / pkinit_crypto_openssl.c en la aplicación PKINIT en el Centro de distribución de claves (KDC) en MIT Kerberos 5 (alias krb5) antes de v1.10.4 y 1.11.x antes de v1.11.1 no trata correctamente los errores durante la extracción de los campos de un certificado X.509, que permite a atacantes remotos provocar una denegación de servicio (desreferencia puntero NULL y la caída del demonio) a través de un formato incorrecto KRB5_PADATA_PK_AS_REQ AS-REQ petición.
It was discovered that Kerberos incorrectly handled certain crafted Draft 9 requests. A remote attacker could use this issue to cause the daemon to crash, resulting in a denial of service.
