## Description

Any project that parses untrusted Protocol Buffers data containing anarbitrary number of nested groups / series of SGROUP tags can corrupted byexceeding the stack limit i.e. StackOverflow. Parsing nested groups asunknown fields with DiscardUnknownFieldsParser or Java Protobuf Liteparser, or against Protobuf map fields, creates unbounded recursions thatcan be abused by an attacker.
