Descriptions

Heap-based buffer overflow in the loadbuf function in formisc.c in formail in procmail 3.22 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted e-mail message because of a hardcoded realloc size, a different vulnerability than CVE-2014-3618.

Desbordamiento de búfer basado en memoria dinámica (heap) en la función loadbuf en formisc.c en formail en la versión 3.22 de procmail permite que atacantes remotos provoquen una denegación de servicio (cierre inesperado de aplicación) o, posiblemente, ejecuten código arbitrario mediante un mensaje de email manipulado debido a un tamaño de realloc embebido. Esta es una vulnerabilidad diferente de CVE-2014-3618.

A heap-based buffer overflow flaw was found in procmail's formail utility. A remote attacker could send a specially crafted email that, when processed by formail, could cause formail to crash or, possibly, execute arbitrary code as the user running formail.
