CVE-2017-5715

TITLE

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

DESCRIPTION

Systems with microprocessors utilizing speculative execution and indirect branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis. 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 a set of firmware that runs in the CPU (Central Processing Unit) for managing and controlling the CPU. The Meltdown vulnerability exists in the CPU processor core, which \"melts\" the security boundary implemented by hardware, allowing low-privileged user-level applications to \"cross-border\" access to system-level memory, causing data leakage. Multiple CPU Hardware are prone to an information-disclosure vulnerability. Attackers can exploit this issue to obtain sensitive information that may aid in further attacks. The following products and versions are affected: ARM Cortex-R7; Cortex-R8; Cortex-A8; Cortex-A9; Cortex-A12; Intel Xeon CPU E5-1650 v3, v2, v4 versions; Xeon E3-1265l v2, v3, v4 Version; Xeon E3-1245 v2, v3, v5, v6 versions; Xeon X7542, etc. Relevant releases/architectures: Image Updates for RHV-H - noarch 3. These packages include redhat-release-virtualization-host, ovirt-node, and rhev-hypervisor. RHVH features a Cockpit user interface for monitoring the host's resources and performing administrative tasks. Security Fix(es): An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions (a commonly used performance optimization). There are three primary variants of the issue which differ in the way the speculative execution can be exploited. Note: This issue is present in hardware and cannot be fully fixed via software update. Please refer to References section for further information about this issue and the performance impact. Variant CVE-2017-5753 triggers the speculative execution by performing a bounds-check bypass. It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory accesses may cause allocation 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 cross the syscall boundary and read privileged memory by conducting targeted cache side-channel attacks. It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory accesses may cause allocation 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 cross the syscall and guest/host boundaries and read privileged memory by conducting targeted cache side-channel attacks. (CVE-2017-5715, Important) Variant CVE-2017-5754 relies on the fact that, on impacted microprocessors, during speculative execution of instruction permission faults, exception generation triggered by a faulting access is suppressed until the retirement of the whole instruction block. In a combination with the fact that memory accesses may populate the cache even when the block is being dropped and never committed (executed), an unprivileged local attacker could use this flaw to read privileged (kernel space) memory by conducting targeted cache side-channel attacks. (CVE-2017-5754, Important) Note: CVE-2017-5754 affects Intel x86-64 microprocessors. AMD x86-64 microprocessors are not affected by this issue. Red Hat would like to thank Google Project Zero for reporting these issues. 6.6) - x86_64 3. Description: Kernel-based Virtual Machine (KVM) is a full virtualization solution for Linux on a variety of architectures. The qemu-kvm package provides the user-space component for running virtual machines that use KVM. (CVE-2017-5715) Note: This is the qemu-kvm side of the CVE-2017-5715 mitigation. Once all virtual machines have shut down, start them again for this update to take effect. Mohamed Ghannam discovered that the IPv4 raw socket implementation in the Linux kernel contained a race condition leading to uninitialized pointer usage. (CVE-2017-17712) ChunYu Wang discovered that a use-after-free vulnerability existed in the SCTP protocol implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code, (CVE-2017-15115) Mohamed Ghannam discovered a use-after-free vulnerability in the DCCP protocol implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. 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. Software Description: - webkit2gtk: Web content engine library for GTK+ Details: It was discovered that speculative execution performed by modern CPUs could leak information through a timing side-channel attack, and that this could be exploited in web browser JavaScript engines. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to obtain sensitive information from other domains, bypassing same-origin restrictions. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: linux-firmware security update Advisory ID: RHSA-2018:0094-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2018:0094 Issue date: 2018-01-16 ===================================================================== 1.

Description: The linux-firmware packages contain all of the firmware files that are required by various devices to operate. This update supersedes microcode provided by Red Hat with the CVE-2017-5715 (aSpectrea) CPU branch injection vulnerability mitigation. (Historically, Red Hat has provided updated microcode, developed by our microprocessor partners, as a customer convenience.) Further testing has uncovered problems with the microcode provided along with the aSpectrea mitigation that could lead to system instabilities. As a result, Red Hat is providing an microcode update that reverts to the last known good microcode version dated before 03 January 2018. Red Hat strongly recommends that customers contact their hardware provider for the latest microcode updates. IMPORTANT: Customers using Intel Skylake-, Broadwell-, and Haswell-based platforms must obtain and install updated microcode from their hardware vendor immediately. The "Spectre" mitigation requires both an updated kernel from Red Hat and updated microcode from your hardware vendor. 4.

Software Description: - linux-azure: Linux kernel for Microsoft Azure Cloud systems - linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems - linux-hwe: Linux hardware enablement (HWE) kernel - linux-oem: Linux kernel for OEM processors Details: USN-3541-1 addressed vulnerabilities in the Linux kernel for Ubuntu 17.10. This update provides the corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 17.10 for Ubuntu 16.04 LTS. This flaw is known as Spectre. A local attacker could use this to expose sensitive information, including kernel memory. This update provides mitigations for the i386 (CVE-2017-5753 only), amd64, ppc64el, and s390x architectures. (CVE-2017-5715, CVE-2017-5753) USN-3523-2 mitigated CVE-2017-5754 (Meltdown) for the amd64 architecture in the Linux Hardware Enablement (HWE) kernel from Ubuntu 17.10 for Ubuntu 16.04 LTS. This update provides the corresponding mitigations for the ppc64el architecture. This flaw is known as Meltdown. A local attacker could use this to expose sensitive information, including kernel memory. (CVE-2017-5754) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 16.04 LTS: linux-image-4.13.0-1006-azure 4.13.0-1006.8 linux-image-4.13.0-1007-gcp 4.13.0-1007.10 linux-image-4.13.0-1017-oem 4.13.0-1017.18 linux-image-4.13.0-31-generic 4.13.0-31.34~16.04.1 linux-image-4.13.0-31-lowlatency 4.13.0-31.34~16.04.1 linux-image-azure 4.13.0.1006.7 linux-image-gcp 4.13.0.1007.9 linux-image-generic-hwe-16.04 4.13.0.31.51 linux-image-gke 4.13.0.1007.9 linux-image-lowlatency-hwe-16.04 4.13.0.31.51 linux-image-oem 4.13.0.1017.21 Please note that fully mitigating CVE-2017-5715 (Spectre Variant 2) requires corresponding processor microcode/firmware updates or, in virtual environments, hypervisor updates. On i386 and amd64 architectures, the IBRS and IBPB features are required to enable the kernel mitigations. Ubuntu users with a processor from a different vendor should contact the vendor to identify necessary firmware updates. Ubuntu will provide corresponding QEMU updates in the future for users of self-hosted virtual environments in coordination with upstream QEMU. Ubuntu users in cloud environments should contact the cloud provider to confirm that the hypervisor has been updated to expose the new CPU features to virtual machines
