Security Vulnerabilities
CVE-2022-42920
- CVE-2022-42920: Apache Commons BCEL prior to 6.6.0 allows producing arbitrary bytecode via out-of-bounds writing.
- Severity: Critical
- CWE-ID: CWE-787
- Vendor: The Apache Software Foundation
- Versions Affected: Apache Commons BCEL before 6.6.0.
- Description: Apache Commons BCEL has a number of APIs that would normally only allow changing specific class characteristics. However, due to an
out-of-bounds writing issue, these APIs can be used to produce arbitrary bytecode. This could be abused in applications that pass
attacker-controllable data to those APIs, giving the attacker more control over the resulting bytecode than otherwise expected. Update to Apache
Commons BCEL 6.6.0.
- Mitigation: Users are recommended to upgrade to version 6.6.0 or later, which fixes the issue.
