An issue was discovered in the FIPS Java API of Bouncy Castle BC-FJA before 1.0.2.4. Changes to the JVM garbage collector in Java 13 and later trigger an issue in the BC-FJA FIPS modules where it is possible for temporary keys used by the module to be zeroed out while still in use by the module, resulting in errors or potential information loss. NOTE: FIPS compliant users are unaffected because the FIPS certification is only for Java 7, 8, and 11.
A flaw was found in the FIPS Java API of Bouncy Castle BC-FJA. Affected versions of this package are vulnerable to Improper Authentication. Changes to the JVM garbage collector in Java 13 and later can trigger an issue in the BC-FJA FIPS modules, where it is possible for temporary keys used by the module to be zeroed out while still in use by the module, resulting in errors or potential information loss.
Отчет
FIPS-compliant users are unaffected because the FIPS certification is only for Java 7, 8, and 11. Within regulated environments, a combination of the following controls acts as a significant barrier to successfully exploiting a CWE-416: Use After Free vulnerability and therefore downgrades the severity of this particular CVE from Moderate to Low. Access to the platform is granted only after successful hard token-based multi-factor authentication (MFA) and is governed by least privilege to ensure that only authorized users and roles can execute or modify code. Red Hat also enforces least functionality, enabling only essential features, services, and ports. Hardening guidelines ensure the most restrictive settings required for operations, while baseline configurations enforce safe memory allocation and deallocation practices to reduce the risk of use-after-free vulnerabilities. The environment employs IPS/IDS and antimalware solutions to detect and prevent malicious code and provide real-time visibility into memory usage, lowering the risk of arbitrary code execution. Static code analysis and peer reviews enforce strong input validation and error handling, reducing the likelihood of denial-of-service (DoS) attacks. In the event of successful exploitation, process isolation prevents a compromised process from accessing memory freed by another, containing potential impact. Finally, memory protection mechanisms such as Data Execution Prevention (DEP) and Address Space Layout Randomization (ASLR) enhance resilience against memory-related vulnerabilities.
