CVE-2022-42920 Information

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.
