CONECTIVA LINUX SECURITY ANNOUNCEMENT 
- --------------------------------------------------------------------------

PACKAGE   : kernel
SUMMARY   : Fixes for kernel vulnerabilities
DATE      : 2004-02-20 14:47:00
ID        : CLA-2004:820
RELEVANT
RELEASES  : 8, 9

DESCRIPTION
 The Linux kernel is responsible for handling the basic functions of
 the GNU/Linux operating system.
 
 Paul Starzetz  identified[1] a new vulnerability[2]
 in the linux memory management code that can be used by local
 attackers to obtain root privileges.
 
 Two other, unrelated, fixes have also been included in this update:
 - CAN-2004-0010[4]: vulnerability in the ncp file system (ncpfs);
 - local kmod denial of service (no CAN alocated to this issue)[5].


SOLUTION
 It is recommended that all users upgrade the kernel packages.
 
 IMPORTANT: exercise caution and preparation when upgrading the
 kernel, since it will require a reboot after the new packages are
 installed. In particular, Conectiva Linux 9 will most likely require
 an initrd file (which is automatically created in the /boot directory
 after the new packages are installed). Generic kernel update
 instructions can be obtained in the manuals and in our faq page[3].
