encoding/xml: stack exhaustion in Decoder.Skip
CVE: CVE-2022-28131
Component: golang
CWE: CWE-1325
Severity: Moderate
CVSS v3: 7.2/AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:H
Release date: 2022-07-12T00:00:00+00:00

A flaw was found in golang encoding/xml. When calling Decoder, Skip while parsing a deeply nested XML document, a panic can occur due to stack exhaustion and allows an attacker to impact system availability.

Statement: The vulnerability exists in the calling of the function decoder.skip to a deeply nested XML document. Although the vulnerability exists, it may require that the application accept deeply nested XML from untrusted sources and specifically calls Decoder.Skip on it. In many deployments, that code path might not even be reachable or exposed to external input. On top of that, a successful exploitation will only result in denial of service due to stack exhaustion, which is why this has been marked as moderate by Red Hat.
