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 <ihaquer@isec.pl> 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].
