Description

In FreeBSD before 11.1-STABLE, 11.1-RELEASE-p9, 10.4-STABLE, 10.4-RELEASE-p8 and 10.3-RELEASE-p28, due to insufficient initialization of memory copied to userland, small amounts of kernel memory may be disclosed to userland processes. Unprivileged users may be able to access small amounts privileged kernel data.
