Product Bulletin: 1074

Subject: CPU/Processor Information Disclosure Vulnerability (Meltdown & Spectre)

Last Update: January 5, 2018

On January 3, 2018 researchers disclosed 3 vulnerabilities that take advantage of speculative execution of instructions performed by many modern microprocessors. These vulnerabilities allow an unprivileged attacker to read privileged memory allocated to the operating system kernel resulting in unintended information disclosure.

Vulnerabilities CVE-2017-5753 and CVE-2017-5715, are collectively known as Spectre, and CVE-2017-5754 is known as Meltdown. The vulnerabilities are variants of the same speculative execution attack, but differ in how they are exploited.

In order to exploit any of these vulnerabilities, an attacker must be able to run crafted code on an affected device. Trend Micro TippingPoint appliances are closed systems, which allows only trusted code provided by TippingPoint to be executed. The underlying CPU and OS combination in TippingPoint products may be affected by these vulnerabilities, however, because these systems are closed with an inability to run arbitrary code, there is no vector to exploit.

Currently there are no known attacks that impact TippingPoint products.

We will continue to monitor the situation and will update this bulletin as appropriate.

DV Filter Update:
Filter 30191 will be released in DV9051 on January 5th, 2018. This filter provides protection against a published remote JavaScript exploit of the vulnerability known as Spectre. TippingPoint will continue to monitor the situation and will release additional filters in future DV's as necessary.

If you have concerns or further questions regarding this issue, contact the Trend Micro TippingPoint Technical Assistance Center (TAC).
