Doc Text:
A flaw was found in protobuf. The protobuf::coded_input_stream::CodedInputStream::skip_group function exhibits uncontrolled recursion when parsing unknown fields from untrusted input, potentially leading to excessive resource consumption. This flaw allows a network attacker to trigger this condition by providing a maliciously crafted Protocol Buffer (protobuf) file. This issue can result in an application-level denial of service due to resource exhaustion.

Description OSIDB Bzimport 2025-07-05 02:01:12 UTC
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.
