Descriptions

The Kerberos 4 support in KDC in MIT Kerberos 5 (krb5kdc) does not properly clear the unused portion of a buffer when generating an error message, which might allow remote attackers to obtain sensitive information, aka "Uninitialized stack values."

El soporte Kerberos 4 en KDC en MIT Kerberos 5 (krb5kdc) no borra apropiadamente la parte no utilizada de un búfer cuando se genera un mensaje de error, lo que podría permitir a los atacantes remotos obtener información confidencial, también se conoce como "Uninitialized stack values."

It was discovered that krb5 did not correctly handle certain krb4 requests. An unauthenticated remote attacker could exploit this flaw by sending a specially crafted traffic, which could expose sensitive information, cause a crash, or execute arbitrary code. A flaw was discovered in the kadmind service's handling of file descriptors. An unauthenticated remote attacker could send specially crafted requests that would cause a crash, resulting in a denial of service. Only systems with configurations allowing large numbers of open file descriptors were vulnerable.
