Garbage collection issue in BC-FJA in Java 13 and later

Moderate severity GitHub Reviewed Published Nov 21, 2022 to the GitHub Advisory Database • Updated Feb 13, 2024

Package

maven org.bouncycastle:bc-fips (Maven)

Affected versions

< 1.0.2.4

Patched versions

1.0.2.4

Description

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.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
