| Descripción: | Description:
The remote host is missing an update to kernel
announced via advisory MDKSA-2004:037.
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.
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:
http://www.mandrakesecure.net/en/kernelupdate.php
Affected versions: 10.0, 9.1, 9.2, Corporate Server 2.1,
Multi Network Firewall 8.2
Solution:
To upgrade automatically use MandrakeUpdate or urpmi. The verification
of md5 checksums and GPG signatures is performed automatically for you.
