Severity ?
Summary
plugins/preauth/pkinit/pkinit_crypto_openssl.c in MIT Kerberos 5 (aka krb5) through 1.15.2 mishandles Distinguished Name (DN) fields, which allows remote attackers to execute arbitrary code or cause a denial of service (buffer overflow and application crash) in situations involving untrusted X.509 data, related to the get_matching_data and X509_NAME_oneline_ex functions. NOTE: this has security relevance only in use cases outside of the MIT Kerberos distribution, e.g., the use of get_matching_data in KDC certauth plugin code that is specific to Red Hat.

Esto permite que atacantes remotos ejecuten c\u00f3digo arbitrario o provoquen una denegaci\u00f3n de servicio (desbordamiento de b\u00fafer y cierre inesperado de la aplicaci\u00f3n) en situaciones relacionadas con datos X.509 no fiables. Esto se relaciona con las funciones get_matching_data y X509_NAME_oneline_ex. NOTA: esto es relevante para la seguridad solo en casos externos a la distribuci\u00f3n de MIT Kerberos, por ejemplo, el uso de get_matching_data en el c\u00f3digo del plugin KDC certauth espec\u00edfico de Red Hat."
