Description
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)
