TITLE

Linux Kernel Vulnerabilities related to authorization, permissions, and access control

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. Linux Kernel Contains vulnerabilities related to authorization, permissions, and access control.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. 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).

Here are the details from the Slackware 14.2 ChangeLog: +--------------------------+ patches/packages/linux-4.4.182/*: Upgraded. These updates fix various bugs and many minor security issues. Be sure to upgrade your initrd after upgrading the kernel packages. If you use lilo to boot your machine, be sure lilo.conf points to the correct kernel and initrd and run lilo as root to update the bootloader. If you use elilo to boot your machine, you should run eliloconfig to copy the kernel and initrd to the EFI System Partition.

For a 32-bit SMP machine, use this command (substitute the appropriate kernel version if you are not running Slackware 14.2): # /usr/share/mkinitrd/mkinitrd_command_generator.sh -k 4.4.186-smp | bash For a 64-bit machine, or a 32-bit uniprocessor machine, use this command (substitute the appropriate kernel version if you are not running Slackware 14.2): # /usr/share/mkinitrd/mkinitrd_command_generator.sh -k 4.4.186 | bash Please note that "uniprocessor" has to do with the kernel you are running, not with the CPU. Most systems should run the SMP kernel (if they can) regardless of the number of cores the CPU has. If you aren't sure which kernel you are running, run "uname -a". If you see SMP there, you are running the SMP kernel and should use the 4.4.186-smp version when running mkinitrd_command_generator. Note that this is only for 32-bit -- 64-bit systems should always use 4.4.186 as the version. If you are using lilo or elilo to boot the machine, you'll need to ensure that the machine is properly prepared before rebooting. If using LILO: By default, lilo.conf contains an image= line that references a symlink that always points to the correct kernel. No editing should be required unless your machine uses a custom lilo.conf. If that is the case, be sure that the image= line references the correct kernel file. Either way, you'll need to run "lilo" as root to reinstall the boot loader. If using elilo: Ensure that the /boot/vmlinuz symlink is pointing to the kernel you wish to use, and then run eliloconfig to update the EFI System Partition. +-----+ Slackware Linux Security Team http://slackware.com/gpg-key security@slackware.com +------------------------------------------------------------------------+ | To leave the slackware-security mailing list: | +------------------------------------------------------------------------+ | Send an email to majordomo@slackware.com with this text in the body of | | the email message: | | | | unsubscribe slackware-security | | | | You will get a confirmation message back containing instructions to | | complete the process.
