MDKSA-2004:037: kernel

Vulnerability Assessment Summary
Check for the version of the kernel package

Detailed Explanation for this Vulnerability Assessment

The remote host is missing the patch for the advisory MDKSA-2004:037 (kernel).


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.
