    "summary": "An issue was discovered in ReadyTalk Avian 1.2.0. The vm::arrayCopy method defined in classpath-common.h returns silently when a negative length is provided (instead of throwing an exception). This could result in data being lost during the copy, with varying consequences depending on the subsequent use of the destination buffer.
