Subject: MDKSA-2004:037 - Updated kernel packages fix multiple vulnerabilities

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

                 Mandrakelinux Security Update Advisory
 _______________________________________________________________________

 Package name:           kernel
 Advisory ID:            MDKSA-2004:037
 Date:                   April 27th, 2004

 Affected versions:	 10.0, 9.1, 9.2, Corporate Server 2.1,
			 Multi Network Firewall 8.2
 ______________________________________________________________________

 Problem 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. (CAN-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.
 (CAN-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(). (CAN-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:
