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 4.1.4
  
• RSA BSAFE Micro Edition Suite - prior to 4.0.13 (in the 4.0.x), and prior to 4.4 (in 4.1.x, 4.2.x and 4.3.x)
