Description

A remote overflow exists in Sendmail. Due to a vulnerable char to int conversion it is possible to use the NOCHAR control value to bypass the length check done by the prescan function resulting in a buffer overflow. With a specially crafted request, an attacker can execute arbitrary code resulting in a loss of integrity.
