CVE-2021-28167 (GCVE-0-2021-28167)

Vulnerability from cvelistv5 – Published: 2021-04-21 17:30 – Updated: 2024-08-03 21:40
VLAI
Summary
In Eclipse Openj9 to version 0.25.0, usage of the jdk.internal.reflect.ConstantPool API causes the JVM in some cases to pre-resolve certain constant pool entries. This allows a user to call static methods or access static members without running the class initialization method, and may allow a user to observe uninitialized values.
Severity
No CVSS data available.

Mitigation
Implementation

Explicitly initialize the resource before use. If this is performed through an API function or standard procedure, follow all specified steps.

Mitigation
Implementation

Pay close attention to complex conditionals that affect initialization, since some branches might not perform the initialization.

Mitigation
Implementation

Avoid race conditions (CWE-362) during initialization routines.

Mitigation
Build and Compilation

Run or compile your product with settings that generate warnings about uninitialized variables or data.

No CAPEC attack patterns related to this CWE.
