Summary
CommuniCrypt Mail versions up to and including 1.16 contains a stack-based buffer overflow vulnerability in its ANSMTP.dll and AOSMTP.dll ActiveX controls, specifically within the AddAttachments() method. This method fails to properly validate the length of input strings, allowing data to exceed the bounds of a fixed-size stack buffer. When invoked with an overly long string, the control can corrupt adjacent memory structures, including exception handlers, leading to potential control flow disruption.

"value": "Las versiones de CommuniCrypt Mail hasta la 1.16 incluida contienen una vulnerabilidad de desbordamiento de b\u00fafer en la pila de sus controles ActiveX ANSMTP.dll y AOSMTP.dll, espec\u00edficamente en el m\u00e9todo AddAttachments(). Este m\u00e9todo no valida correctamente la longitud de las cadenas de entrada, lo que permite que los datos excedan los l\u00edmites de un b\u00fafer de pila de tama\u00f1o fijo. Al invocarse con una cadena demasiado larga, el control puede corromper las estructuras de memoria adyacentes, incluyendo los manejadores de excepciones, lo que puede provocar una interrupci\u00f3n del flujo de control."
