Overview
Affected versions of this package are vulnerable to Integer Overflow or Wraparound in ProtobufParser.java. An attacker can crash the process with an OutOfMemoryError by sending a Protobuf message of about 33 bytes with a string or bytes length near Integer.MAX_VALUE, which bypasses the bounds check and makes the parser allocate an array of that size. Only services that parse untrusted Protobuf input are exposed, and neither heap tuning nor StreamReadConstraints limits the allocation.
