Package : linux-4.9
Version : 4.9.168-1+deb9u4~deb8u1
CVE ID : CVE-2019-13272

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.
