CVE-2019-13272

TITLE

Linux kernel Permission Licensing and Access Control Issue Vulnerability

DESCRIPTION

In the Linux kernel before 5.1.17, ptrace_link in kernel/ptrace.c mishandles the recording of the credentials of a process that wants to create a ptrace relationship, which allows local users to obtain root access by leveraging certain scenarios with a parent-child process relationship, where a parent drops privileges and calls execve (potentially allowing control by an attacker). One contributing factor is an object lifetime issue (which can also cause a panic). Another contributing factor is incorrect marking of a ptrace relationship as privileged, which is exploitable through (for example) Polkit's pkexec helper with PTRACE_TRACEME. NOTE: SELinux deny_ptrace might be a usable workaround in some environments. 8) - aarch64, noarch, ppc64le, s390x, x86_64 3. 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).

ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.
