[slackware-security]  Slackware 8.1 kernel security update  (SSA:2004-008-01)

New kernels are available for Slackware 8.1 containing a
backported fix from a bounds-checking problem in the kernel's
mremap() call which could be used by a local attacker to gain
root privileges.  This fix was previously issued for Slackware
9.0, 9.1, and -current (SSA:2004-006-01).

Sites running Slackware 8.1 should upgrade to the new kernel.
After installing the new kernel, be sure to run 'lilo'.

More details about this issue may be found in the Common
Vulnerabilities and Exposures (CVE) database:

INSTALLATION INSTRUCTIONS:
+------------------------+

Use upgradepkg to install the new kernel, kernel-modules, and alsa packages.
After installing the kernel-ide package you will need to run lilo ('lilo' at
a command prompt) or create a new system boot disk ('makebootdisk'), and
reboot.

If desired, a kernel from the kernels/ directory may be used instead.  For
example, to use the kernel in kernels/scsi.s/, you would copy it to the
boot directory like this:

cd kernels/scsi.s
cp bzImage /boot/vmlinuz-scsi.s-2.4.18

Create a symbolic link:
ln -sf /boot/vmlinuz-scsi.s-2.4.18 /boot/vmlinuz

Then, run 'lilo' or create a new system boot disk and reboot.
