Mandrake Linux Security Advisory : kernel (MDKSA-2004:037)

high Nessus Plugin ID 14136

Synopsis

The remote Mandrake Linux host is missing one or more security updates.

Description

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)
