This security bulletin contains information about 1 security vulnerability.


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

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)
