Descriptions

Attackers with access to user accounts can inject arbitrary control characters to SIEVE mail-filter rules. This could be abused to access SIEVE extension that are not allowed by App Suite or to inject rules which would break per-user filter processing, requiring manual cleanup of such rules. We have added sanitization to all mail-filter APIs to avoid forwardning control characters to subsystems. No publicly available exploits are known.

Los atacantes con acceso a cuentas de usuario pueden inyectar caracteres de control arbitrarios a las reglas del filtro de correo SIEVE. Esto podría ser abusado para acceder a extensiones de SIEVE que no están permitidas por App Suite o para inyectar reglas que romperían el procesamiento de filtros por usuario, requiriendo la limpieza manual de dichas reglas. Se han añadido desinfección a todas las API del filtro de correo para evitar el reenvío de caracteres de control a los subsistemas. No se conocen exploits disponibles públicamente.
