1) Information Exposure Through Timing Discrepancy (CVE-ID: CVE-2019-3732)

CWE-ID: CWE-208 - Information Exposure Through Timing Discrepancy

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to two separate operations in a product require different amounts of time to complete, in a way that is observable to an actor and reveals security-relevant information about the state of the product. A remote attacker can extract information leaving data at risk of exposure.

This vulnerability affects the following versions:

RSA BSAFE Crypto-C Micro Edition - versions prior to 4.0.5.3 (in 4.0.x) and prior to 4.1.3.3 (in 4.1.x)
RSA BSAFE Micro Edition Suite - versions prior to 4.0.11 (in 4.0.x), prior to 4.1.6.1 (in 4.1.x) and versions prior to 4.3.3 (4.2.x and 4.3.x)

Remediation

Install update from vendor's website.
