The shmat system call in the System V Shared Memory interface for
FreeBSD 5.2 and earlier, NetBSD 1.3 and earlier, and OpenBSD 2.6 and
earlier, does not properly decrement a shared memory segment's
reference count when the vm_map_find function fails, which could allow
local users to gain read or write access to a portion of kernel memory
and gain privileges.
