linux-4.9 - security update

Description

Jann Horn discovered that the ptrace subsystem in the Linux kernel mishandles the management of the credentials of a process that wants to create a ptrace relationship, allowing a local user to obtain root privileges under certain scenarios. For Debian 8 Jessie, this problem has been fixed in version 4.9.168-1+deb9u4~deb8u1. We recommend that you upgrade your linux-4.9 packages. Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: <https://wiki.debian.org/LTS>
