CVE-2018-3639

TITLE

CPU hardware utilizing speculative execution may be vulnerable to cache side-channel attacks

DESCRIPTION

Systems with microprocessors utilizing speculative execution and speculative execution of memory reads before the addresses of all prior memory writes are known may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis, aka Speculative Store Bypass (SSB), Variant 4. CPU hardware utilizing speculative execution may be vulnerable to cache timing side-channel analysis. Two vulnerabilities are identified, known as "Variant 3a" and "Variant 4". CPUhardware is firmware that runs in the central processor for managing and controlling the CPU. Multiple CPUHardware information disclosure vulnerabilities. The vulnerability is caused by a race condition in the CPU cache processing. Local attackers can exploit vulnerabilities to obtain sensitive information through side channel analysis. AMD, ARM, and Intel CPUs are all CPU (central processing unit) products from different manufacturers. AMD, ARM, and Intel CPUs have security vulnerabilities. On Intel CPUs this requires updated microcode which is currently not released publicly (but your hardware vendor may have issued an update). For servers with AMD CPUs no microcode update is needed, please refer to https://xenbits.xen.org/xsa/advisory-263.html for further information. For the stable distribution (stretch), this problem has been fixed in version 4.8.3+xsa262+shim4.10.0+comet3-1+deb9u7. We recommend that you upgrade your xen packages.

Summary: An update for kernel is now available for Red Hat Enterprise Linux 7.2 Advanced Update Support, Red Hat Enterprise Linux 7.2 Telco Extended Update Support, and Red Hat Enterprise Linux 7.2 Update Services for SAP Solutions. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Server AUS (v. 7.2) - noarch, x86_64 Red Hat Enterprise Linux Server E4S (v. 7.2) - noarch, ppc64le, x86_64 Red Hat Enterprise Linux Server Optional AUS (v. 7.2) - x86_64 Red Hat Enterprise Linux Server Optional E4S (v. 7.2) - ppc64le, x86_64 Red Hat Enterprise Linux Server Optional TUS (v. 7.2) - x86_64 Red Hat Enterprise Linux Server TUS (v. 7.2) - noarch, x86_64 3. Description: The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): * An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of Load & Store instructions (a commonly used performance optimization). It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory read from address to which a recent memory write has occurred may see an older value and subsequently cause an update into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). As a result, an unprivileged attacker could use this flaw to read privileged memory by conducting targeted cache side-channel attacks. (CVE-2018-3639, x86 AMD) Red Hat would like to thank Ken Johnson (Microsoft Security Response Center) and Jann Horn (Google Project Zero) for reporting this issue. Bug Fix(es): * When switching from the indirect branch speculation (IBRS) feature to the retpolines feature, the IBRS state of some CPUs was sometimes not handled correctly. Consequently, some CPUs were left with the IBRS Model-Specific Register (MSR) bit set to 1, which could lead to performance issues. With this update, the underlying source code has been fixed to clear the IBRS MSR bits correctly, thus fixing the bug. (BZ#1586145) 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 The system must be rebooted for this update to take effect. 5.

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 4.4.144-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 4.4.144 | 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 4.4.144-smp version when running mkinitrd_command_generator. Note that this is only for 32-bit -- 64-bit systems should always use 4.4.144 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.

Description: The libvirt library contains a C API for managing and interacting with the virtualization capabilities of Linux and other operating systems. In addition, libvirt provides tools for remote management of virtualized systems. 6) - i386, x86_64 3. Description: Kernel-based Virtual Machine (KVM) is a full virtualization solution for Linux on a variety of architectures. The qemu-kvm packages provide the user-space component for running virtual machines that use KVM. (CVE-2018-3639) Note: This is the qemu-kvm side of the CVE-2018-3639 mitigation. Once all virtual machines have shut down, start them again for this update to take effect. VDSM manages and monitors the host's storage, memory and networks as well as virtual machine creation, other host administration tasks, statistics gathering, and log collection
