> integer overflow in IP_MSFILTER

> An integer overflow in computing the size of a temporary buffer can
> result in a buffer which is too small for the requested operation.

> An unprivileged process can read or write pages of memory which
> belong to the kernel.  These may lead to exposure of sensitive
> information or allow privilege escalation.

kfreebsd-8 and kfreebsd-9 in wheezy will need the patch from r254629

kfreebsd-9 in jessie/sid will need updating to r254630 or later

kfreebsd-10 in experimental will need updating to r254629 or later

kfreebsd-8 8.1 in oldstable looks to be affected too (likely introduced
in r189592 or earlier).  The same patch should be suitable.
