Prototype Pollution in protobufjs

The package protobufjs is vulnerable to Prototype Pollution, which can allow an attacker to add/modify properties of the Object.prototype. Versions after and including 6.10.0 until 6.10.3 and after and including 6.11.0 until 6.11.3 are vulnerable.

This vulnerability can occur in multiple ways:

1. by providing untrusted user input to util.setProperty or to ReflectionObject.setParsedOption functions
2. by parsing/loading .proto files
