GHSA-rxf6-323f-44fc: rust-protobuf crate is vulnerable to Uncontrolled Recursion, potentially leading to DoS
The protobuf crate before 3.7.2 for Rust allows uncontrolled recursion in the protobuf::coded_input_stream::CodedInputStream::skip_group parsing of unknown fields in untrusted input.
Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
