Description:
While a programming error in the kernel may be subject to direct
exploitation, usually a more roundabout approach is required to take
advantage of a security bug. One popular approach for those wishing to
take advantage of vulnerabilities is heap spraying , and
it has often been employed to compromise the kernel. In the future,
though, heap-spraying attacks may be a bit harder to pull off, thanks to the "dedicated bucket allocator" proposed by Kees Cook.
