An out-of-bounds write vulnerability exists in the SetAttributeList attribute_count_request functionality of EIP Stack Group OpENer development commit 58ee13c. A specially crafted EtherNet/IP request can lead to an out of bounds write, potentially causing the server to crash or allow for remote code execution. An attacker can send a series of EtherNet/IP requests to trigger this vulnerability.

Apache Commons BCEL prior to 6.6.0 allows producing arbitrary bytecode via out-of-bounds writing

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.
