There is a vulnerability in Sendmail versions 8.12.8 and prior. The
address parser performs insufficient bounds checking in certain conditions
due to a char to int conversion, making it possible for an attacker to
take control of the application. Although no exploit currently exists,
this issue is probably locally exploitable and may be remotely exploitable.
