Hi,

The following vulnerability was published for rust-protobuf.

CVE-2024-7254[0]:
| Any project that parses untrusted Protocol Buffers data containing
| an arbitrary number of nested groups / series of SGROUP tags can
| corrupted by exceeding the stack limit i.e. StackOverflow. Parsing
| nested groups as unknown fields with DiscardUnknownFieldsParser or
| Java Protobuf Lite parser, or against Protobuf map fields, creates
| unbounded recursions that can be abused by an attacker.


If you fix the vulnerability please also make sure to include the
