commands.c in qmail, when running on 64 bit platforms with a large amount
of virtual memory, allows remote attackers to cause a denial of service and
possibly execute arbitrary code via a long SMTP command without a space
character, which causes an array to be referenced with a negative index.
It was discovered that netqmail did not properly handle certain input. Both
remote and local attackers could use this vulnerability to cause netqmail to
crash or execute arbitrary code.
