Security Bulletin
Summary
OpenSSL as used in IBM QRadar Network Packet Capture is susceptible to information exposure.
Vulnerability Details
CVEID: CVE-2018-5407
Description: Multiple SMT/Hyper-Threading architectures and processors could allow a local attacker to obtain sensitive information, caused by execution engine sharing on Simultaneous Multithreading (SMT) architecture. By using the new PortSmash side-channel attack, an attacker could run a malicious process next to legitimate processes using the architectures parallel thread running capabilities to leak encrypted data from the CPU's internal processes. Note: This vulnerability is known as PortSmash.
CVSS Base Score: 5.1
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/152484 for the current score
CVSS Environmental Score: *Undefined
