Security Bulletin: OpenSSL as used in IBM QRadar Network Packet Capture is vulnerable to information exposure (CVE-2018-5407)

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.
