[slackware-security] kernel (SSA:2017-258-02)

New kernel packages are available for Slackware 14.1, 14.2, and -current to
fix a security issue.


Here are the details from the Slackware 14.2 ChangeLog:
+--------------------------+
patches/packages/linux-4.4.88/*: Upgraded.
This update fixes the security vulnerability known as "BlueBorne".
The native Bluetooth stack in the Linux Kernel (BlueZ), starting at
Linux kernel version 3.3-rc1 is vulnerable to a stack overflow in
the processing of L2CAP configuration responses resulting in remote
code execution in kernel space.
Be sure to upgrade your initrd after upgrading the kernel packages.
If you use lilo to boot your machine, be sure lilo.conf points to the correct
kernel and initrd and run lilo as root to update the bootloader.
If you use elilo to boot your machine, you should run eliloconfig to copy the
kernel and initrd to the EFI System Partition.
For more information, see:

Installation instructions:
+------------------------+

Upgrade the packages as root:
# upgradepkg kernel-*.txz

If you are using an initrd, you'll need to rebuild it.

For a 32-bit SMP machine, use this command (substitute the appropriate
kernel version if you are not running Slackware 14.2):
# /usr/share/mkinitrd/mkinitrd_command_generator.sh -k 4.4.88-smp | bash

For a 64-bit machine, or a 32-bit uniprocessor machine, use this command
(substitute the appropriate kernel version if you are not running
Slackware 14.2):
# /usr/share/mkinitrd/mkinitrd_command_generator.sh -k 4.4.88 | bash

Please note that "uniprocessor" has to do with the kernel you are
running,
not with the CPU. Most systems should run the SMP kernel (if they can)
regardless of the number of cores the CPU has. If you aren't sure which
kernel you are running, run "uname -a". If you see SMP there, you are
running the SMP kernel and should use the 4.4.88-smp version when running
mkinitrd_command_generator. Note that this is only for 32-bit -- 64-bit
systems should always use 4.4.88 as the version.

If you are using lilo to boot the machine, you'll need to ensure that the
machine is properly prepared before rebooting. Be sure that the image= line
references the correct kernel file and then run "lilo" as root to
reinstall
the boot loader.
