Crash due to uncontrolled recursion in protobuf crate

Details
Package	protobuf
Version	2.28.0
URL	stepancheg/rust-protobuf#749
Date	2024-12-12

Affected version of this crate did not properly parse unknown fields when parsing a user-supplied input.

This allows an attacker to cause a stack overflow when parsing the mssage on untrusted data.

See advisory page for additional details.
