Security Bulletin: OpenSSL as used by IBM QRadar Network Packet Capture is vulnerable to a timing side channel attack (CVE-2018-0734)

Summary

Covert timing channels convey information by modulating some aspect of system behavior over time, so that the program receiving the information can observe system behavior and infer protected information.

Vulnerability Details

CVEID:CVE-2018-0734
**DESCRIPTION:**The OpenSSL DSA signature algorithm has been shown to be vulnerable to a timing side channel attack. An attacker could use variations in the signing algorithm to recover the private key. Fixed in OpenSSL 1.1.1a (Affected 1.1.1). Fixed in OpenSSL 1.1.0j (Affected 1.1.0-1.1.0i). Fixed in OpenSSL 1.0.2q (Affected 1.0.2-1.0.2p).
