TITLE

Multiple Intel Product Information Disclosure Vulnerabilities (CNVD-2019-22233)

DESCRIPTION

Microarchitectural Fill Buffer Data Sampling (MFBDS): Fill buffers on some microprocessors utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access. A list of impacted products can be found here: https://www.intel.com/content/dam/www/public/us/en/documents/corporate-information/SA00233-microcode-update-guidance_05132019.pdf. Intel Xeon Scalable Processors and so on are products of Intel Corporation of the United States. Intel XeonScalable Processors is a scalable server central processing unit (CPU). IntelXeonProcessorE7v4Family is a XeonE7 series server central processing unit (CPU). IntelXeonProcessorE5v4Family is a XeonE5 series server central processing unit (CPU). An information disclosure vulnerability exists in several Intel products. The vulnerability stems from errors in the configuration of the network system or product during operation. An unauthorized attacker can exploit the vulnerability to obtain sensitive information about the affected component. The following products and versions are affected: Intel Xeon Scalable Processors; Xeon Processor E7 v4 Family; Xeon Processor E5 v4 Family; Xeon Processor E3 v6 Family; Xeon Processor E3 v4 Family; Xeon Processor E; Xeon E Processor; Xeon D Processor; Puma; Pentium Processor Silver Series; Pentium Processor N Series; Pentium Processor J Series; Pentium Gold Processor Series; Mobile Communications Platforms; Microcode; Core X series Processors; Celeron Processor N Series; Celeron Processor J Series; Celeron Processor G Series; Atom Processor X Series ;Atom Processor E3900 Series;Atom Processor E3800 Series;Atom Processor. The vulnerability is due to improper memory operations that could expose a side channel on the affected system. A successful exploit could be used to conduct further attacks. Proof-of-concept (PoC) code that demonstrates an exploit of this vulnerability is publicly available. A third-party patch is also available. Description: KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on a variety of architectures. The qemu-kvm-rhev packages provide the user-space component for running virtual machines that use KVM in environments managed by Red Hat products.

Summary: An update for kernel is now available for Red Hat Enterprise Linux 7. 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 Client (v. 7) - noarch, x86_64 Red Hat Enterprise Linux Client Optional (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode (v. 7) - noarch, x86_64 Red Hat Enterprise Linux ComputeNode Optional (v. 7) - x86_64 Red Hat Enterprise Linux Server (v. 7) - noarch, ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 7) - ppc64, ppc64le, x86_64 Red Hat Enterprise Linux Workstation (v. 7) - noarch, x86_64 Red Hat Enterprise Linux Workstation Optional (v. 7) - x86_64 3. Description: The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): * A flaw was found in the implementation of the "fill buffer", a mechanism used by modern CPUs when a cache-miss is made on L1 CPU cache. If an attacker can generate a load operation that would create a page fault, the execution will continue speculatively with incorrect data from the fill buffer while the data is fetched from higher level caches. This response time can be measured to infer data in the fill buffer. (CVE-2018-12130) * Modern Intel microprocessors implement hardware-level micro-optimizations to improve the performance of writing data back to CPU caches. The write operation is split into STA (STore Address) and STD (STore Data) sub-operations. These sub-operations allow the processor to hand-off address generation logic into these sub-operations for optimized writes. Both of these sub-operations write to a shared distributed processor structure called the 'processor store buffer'. As a result, an unprivileged attacker could use this flaw to read private data resident within the CPU's processor store buffer. (CVE-2018-12126) * Microprocessors use a ‘load port’ subcomponent to perform load operations from memory or IO. During a load operation, the load port receives data from the memory or IO subsystem and then provides the data to the CPU registers and operations in the CPU’s pipelines. Stale load operations results are stored in the 'load port' table until overwritten by newer operations. Certain load-port operations triggered by an attacker can be used to reveal data about previous stale requests leaking data back to the attacker via a timing side-channel. (CVE-2019-11091) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section. 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.
