CVE-2022-42920 — Vulnerability in org.apache.bcel:bcel — CVE Details

CRITICAL

Apache Commons BCEL vulnerable to out-of-bounds write

Published November 7, 2022Updated February 16, 2024Source: osv

Summary

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.
