libbcel-java: Apache Commons BCEL has a number of APIs that would normally only allow changing specific class characteristics
CVE-2022-42920 is fixed in 3 products on 1 platform, first by libbcel-java 6.2-1ubuntu0.1~esm1, released November 7, 2022. It is not reported as exploited. Patch Radar priority: High.
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.
