Do I need to upgrade my kernel (kernel-image-2.4-k6)?

[Robert S]

I am running debian with kernel 2.4.27.  I see that the kernel-source package is listed in the security vulnerabilities (DSA-1097).  I do a weekly "apt-get update && apt-get upgrade" but have not been prompted to upgrade my kernel.  I am using kernel-image-2.4-k6.

Do I need to upgrade my kernel image and if so, what is the correct way of doing this?
