Descriptions

The TNEFFillMapi function in lib/ytnef.c in libytnef in ytnef through 1.9.2 does not ensure a nonzero count value before a certain memory allocation, which allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted tnef file.

La función TNEFFillMapi en lib / ytnef.c en libytnef in ytnef hasta 1.9.2 no garantiza un valor de conteo distinto de cero antes de una cierta asignación de memoria, lo que permite a los atacantes remotos causar una denegación de servicio (desbordamiento de buffer basado en saturación y bloqueo de la aplicación) o posiblemente tenga otro impacto no especificado a través de un archivo tnef diseñado.
