Summary

IBM QRadar Network Security has addressed the following CPU vulnerability.

Vulnerability Details

CVEID:CVE-2018-3620
DESCRIPTION: Multiple Intel CPU’s could allow a local attacker to obtain sensitive information, caused by a flaw in the CPU speculative branch instruction execution feature. By conducting targeted cache side-channel attacks and via a terminal page fault, an attacker could exploit this vulnerability to leak information residing in the L1 data cache and read data belonging to different security contexts. Note: This vulnerability is also known as the “L1 Terminal Fault (L1TF)” or “Foreshadow” attack.
CVSS Base Score: 7.1
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/148318&gt; for the current score
CVSS Environmental Score*: Undefined
