Descriptions

A flaw was found in IPA, all 4.6.x versions before 4.6.7, all 4.7.x versions before 4.7.4 and all 4.8.x versions before 4.8.3, in the way the internal function ber_scanf() was used in some components of the IPA server, which parsed kerberos key data. An unauthenticated attacker who could trigger parsing of the krb principal key could cause the IPA server to crash or in some conditions, cause arbitrary code to be executed on the server hosting the IPA server.

Se encontró un fallo en IPA, todas las versiones 4.6.x anteriores a la versión 4.6.7, todas las versiones 4.7.x anteriores a la 4.7.4 y todas las versiones 4.8.x anteriores a 4.8.3, en la manera en que la API de procesamiento por lotes de FreeIPA registró operaciones. Esto incluía pasar contraseñas de usuario en texto sin cifrar en los maestros de FreeIPA. El procesamiento por lotes de comandos con contraseñas como argumentos u opciones no se realiza por defecto en FreeIPA, pero es posible mediante componentes de terceros. Un atacante que tenga acceso a los registros del sistema en los maestros de FreeIPA podría usar este fallo para producir el contenido del archivo de registro con las contraseñas expuestas.
