Package        : linux
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 the oldstable distribution (stretch), this problem has been fixed
in version 4.9.168-1+deb9u4.

For the stable distribution (buster), this problem has been fixed in
version 4.19.37-5+deb10u1. This update includes as well a patch for a
regression introduced by the original fix for CVE-2019-11478 (#930904).

We recommend that you upgrade your linux packages.
