This is a feature. Some ping programs (like the Win95) allow you to create
packets that are larger than allowed for in the relevant standard. These
packets could be used to crash some systems, including older Linux kernels.
Newer kernel versions, like the ones used in Debian 1.3.1r6, were fixed. As
oversized ping packets could be used as an attack, the kernel reports them.
