Summary:

A potential security vulnerability in some microprocessors may allow partial information disclosure via local access.

Vulnerability Details:

CVEID: CVE-2019-0174
Description: Logic condition in specific microprocessors may allow an authenticated user to potentially enable partial physical address information disclosure via local access.
CVSS Base Score: 3.8 Low
CVSS Vector: CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:N

Affected Products:

Microprocessors:
Intel® Core™ X-series Processors, 4th Generation Intel® Core™ i5 Processors,4th Generation Intel® Core™ i3 Processors, Intel® Pentium® Processor G Series, Intel® Pentium® Processor 3000 Series, Intel® Celeron® Processor 2000 Series, Intel® Xeon® Processor E7 v3 Family, Intel® Xeon® Processor E5 v3 Family, Intel® Xeon® Processor E3 v3 Family.

Recommendations:

Partial physical address information potentially disclosed through exploitation of this vulnerability does not contain user secrets, but could potentially be utilized to enhance unrelated attack methods. For published exploits that Intel is aware of, Intel recommends users follow existing best practices including:

The use of DRAM modules resistant to Rowhammer style attacks.

Security Best Practices For Side Channel Resistance:

Security Best Practices for Side Channel Resistance

Guidelines For Mitigating Timing Side Channels Against Cryptographic Implementations:

Acknowledgements:

Intel would like to thank Andrew Kwong, Daniel Genkin from University of Michigan and Daniel Gruss from Graz University of Technology and Yuval Yarom from University of Adelaide and Data61 for reporting this issue.

Intel, and nearly the entire technology industry, follows a disclosure practice called Coordinated Disclosure, under which a cybersecurity vulnerability is generally publicly disclosed only after mitigations are available.

More Intel Processor Vulnerabilities

[table][tr]Intel ID: INTEL-SA-00161 [/tr] [tr][td]Product family:[/td] [td]Multiple[/td] [/tr] [tr][td]Impact of vulnerability:[/td] [td]Information Disclosure[/td] [/tr] [tr][td]Severity rating:[/td] [td]See Security Advisory text[/td] [/tr] [tr][td]Original release:[/td] [td]08/14/2018[/td] [/tr] [tr][td]Last revised:[/td] [td]08/14/2018[/td] [/tr] [/table]

Summary:

Security researchers have identified a speculative execution side-channel method called L1 Terminal Fault (L1TF). This method impacts select microprocessor products supporting Intel® Software Guard Extensions (Intel® SGX). Further investigation by Intel has identified two related applications of L1TF with the potential to impact additional microprocessors, operating systems, system management mode, and virtualization software. If used for malicious purposes, this class of vulnerability has the potential to improperly infer data values from multiple types of computing devices.

Intel is committed to product and customer security and to coordinated disclosure. We worked closely with other technology companies, operating system, and hypervisor software vendors, developing an industry-wide approach to mitigate these issues promptly and constructively.

Recommendations:

Intel has worked with operating system vendors, equipment manufacturers, and other ecosystem partners to develop platform firmware and software updates that can help protect systems from these methods.

This includes the release of updated Intel microprocessor microcode to our customers and partners. This microcode was previously released as part of INTEL-SA-00115.

Status of available microcode can be found here.

End users and systems administrators should check with their system manufacturers and system software vendors and apply any available updates as soon as practical.
