Description

A flaw was found in golang. Calling Unmarshal on an XML document into a Go struct, which has a nested field that uses the "any" field tag, can cause a panic due to stack exhaustion.

Statement

Red Hat has marked this as moderate impact for two primary reasons

  1. Though the vulnerability exists, it is hard to exploit in real scenarios (e.g., the attacker must be able to feed crafted XML documents into specific code paths).
  2. The vulnerability is a denial of service (DoS) due to stack exhaustion rather than code execution or data breach. Since it doesn’t compromise confidentiality or integrity.
