DESCRIPTION
The Linux kernel is responsible for handling the basic functions of
the GNU/Linux operating system.
Paul Starzetz <ihaquer (at) isec (dot) pl [email concealed]> 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].
ADDITIONAL INSTRUCTIONS
The apt tool can be used to perform RPM packages upgrades:
- run: apt-get update
- after that, execute: apt-get upgrade
Detailed instructions regarding the use of apt and upgrade examples
can be found at http://distro.conectiva.com.br/atualizacoes/#apt?idioma=en

All packages are signed with Conectiva's GPG key. The key and instructions
on how to import it can be found at

Instructions on how to check the signatures of the RPM packages can be
