"A vulnerability was found in the framebuffer driver of the 2.6 kernel.
This is due to incorrect use of the fb_copy_cmap function.
(CVE-2004-0229)

A vulnerability has been found in the Linux kernel in the
ip_setsockopt() function code. There is an exploitable integer
overflow inside the code handling the MCAST_MSFILTER socket option in
the IP_MSFILTER_SIZE macro calculation. This issue is present in both
2.4 (2.4.25) and 2.6 kernels. (CVE-2004-0424)

There is a minor issue with the static buffer in 2.4 kernel's panic()
function. Although it's a possibly buffer overflow, it most like not
exploitable due to the nature of panic(). (CVE-2004-0394)

In do_fork(), if an error occurs after the mm_struct for the child has
been allocated, it is never freed. The exit_mm() meant to free it
increments the mm_count and this count is never decremented. (For a
running process that is exitting, schedule() takes care this; however,
the child process being cleaned up is not running.) In the CLONE_VM
case, the parent's mm_struct will get an extra mm_count and so it will
never be freed. This issue is present in both 2.4 and 2.6 kernels.
(CVE-2004-0427)

The provided packages are patched to fix these vulnerabilities. All
users are encouraged to upgrade to these updated kernels.

To update your kernel, please follow the directions located at :
