Description Summary:
The Bouncy Castle for Java library is susceptible to a timing discrepancy vulnerability during cryptographic operations, potentially allowing for side-channel information leakage.
Executive Summary:
A timing side-channel vulnerability in the Bouncy Castle for Java library may allow attackers to infer sensitive cryptographic information.
Vulnerability Details
CVE-ID: CVE-2024-14041
Affected Software: Legion of the Bouncy Castle Inc. BC-JAVA
Affected Versions: 1.73 up to (excluding) 1.78
Vulnerability: This is an observable timing discrepancy (CWE-208) flaw. It is an unauthenticated vulnerability that can be triggered remotely, though it requires specific conditions to be met for successful exploitation.
Business Impact
The vulnerability poses a significant risk to the confidentiality of encrypted communications or stored data. If an attacker can accurately measure the timing of cryptographic operations, they may recover sensitive keys or plaintext, potentially undermining the security posture of any application relying on this library.
Remediation Plan
Immediate Action: Update the Bouncy Castle for Java library to version 1.78 or newer to incorporate the necessary timing mitigations.
Proactive Monitoring: Review application performance logs for unusual latency patterns in cryptographic modules that might indicate an ongoing side-channel attack.
Compensating Controls: Where patching is not immediately feasible, isolate the affected applications to environments with minimal network exposure to reduce the feasibility of timing measurements.
Exploitation Status
Public Exploit Available: No.
Analyst Notes: As of July 28, 2026, there is no public information indicating active exploitation or a public proof-of-concept for this vulnerability. Timing side-channels are inherently complex to exploit in real-world network conditions.
Analyst Recommendation
Developers should prioritize upgrading to the latest version of the Bouncy Castle library to protect against potential side-channel attacks. Ensuring that cryptographic implementations are resistant to timing discrepancies is essential for maintaining the integrity of secure data transmissions.
