Descriptions

A vulnerability in the MIME message handling of the Notes client (versions 9 and 10) could potentially be exploited by an unauthenticated attacker resulting in a stack buffer overflow. This could allow a remote attacker to crash the client or inject code into the system which would execute with the privileges of the client.

Una vulnerabilidad en el manejo de mensajes MIME del cliente Notes (versiones 9 y 10), podría potencialmente ser explotada por un atacante no autenticado, resultando en un desbordamiento del búfer de pila. Esto podría permitir a un atacante remoto bloquear el cliente o inyectar código en el sistema que se ejecutaría con los privilegios del cliente.
