CVE-2024-24786

A flaw was found in golang-protobuf. The protojson unmarshaling function can enter an infinite loop when parsing certain invalid JSON inputs, specifically when decoding messages containing Any values or when configured to discard unknown fields. A remote attacker can exploit this vulnerability by submitting specially crafted JSON payloads to cause excessive CPU utilization and hang the application, resulting in a Denial of Service (DoS).

This vulnerability is rated as Moderate impact because exploitation is restricted to denial of service via excessive CPU and thread consumption, without compromising data confidentiality or system integrity. Red Hat services and containerized components are only exposed if they process untrusted JSON inputs into Protocol Buffer structures configured with specific parsing behaviors. Under typical deployments, the flaw does not grant privileged access or permit arbitrary code execution.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
