Descriptions

An issue was discovered in MIT Kerberos 5 (aka krb5) through 1.16. There is a variable "dbentry->n_key_data" in kadmin/dbutil/dump.c that can store 16-bit data but unknowingly the developer has assigned a "u4" variable to it, which is for 32-bit data. An attacker can use this vulnerability to affect other artifacts of the database as we know that a Kerberos database dump file contains trusted data.

Se ha descubierto un problema en MIT Kerberos 5 (también conocido como krb5) hasta la versión 1.16. Hay una variable "dbentry->n_key_data" en kadmin/dbutil/dump.c que puede almacenar datos en 16 bits pero, sin saberlo, el desarrollador le ha asignado una variable "u4", que es para datos en 32 bits. Un atacante puede emplear esta vulnerabilidad para afectar a otros artefactos de la base de datos, ya que se sabe que un archivo de volcado de base de datos de Kerberos contiene datos fiables.
