FreeBSD -- Local kernel memory disclosure

Problem description:
A buffer allocated from the kernel stack may not be completely
initialized before being copied to userland. [CVE-2006-0379]
A logic error in computing a buffer length may allow too much
data to be copied into userland. [CVE-2006-0380]
Impact:
Portions of kernel memory may be disclosed to local users.
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.
Workaround:
No workaround is available.
