Problem Description:
Due to insufficient initialization of memory copied to
userland in the components listed above small amounts of
kernel memory may be disclosed to userland processes.
Impact:
A user who can invoke 32-bit FreeBSD ioctls may be able
to read the contents of small portions of kernel memory.
Such memory might contain sensitive information, such
as portions of the file cache or terminal buffers. This
information might be directly useful, or it might be leveraged
to obtain elevated privileges in some way; for example, a
terminal buffer might include a user-entered password.
