Multiple buffer overflows in Hypermail 2 before 2.1.6 allows remote attackers to cause a denial of service and possibly execute arbitrary code (1) via a long attachment filename that is not properly handled by the hypermail executable, or (2) by connecting to the mail CGI program from an IP address that reverse-resolves to a long hostname.
