    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.
