Root Cause Analysis
The vulnerability is explicitly attributed to the guard()
function in multiple sources: 1) The CVE title directly references guard()
2) The commit diff shows critical modifications to the guard()
function's depth tracking logic 3) The advisory describes how improper depth counting in guard()
leads to XML context confusion 4) The patch specifically restructures guard()
's error handling and depth management. The function's role in managing XML parser event routing makes it the clear vulnerability source when combined with error suppression mechanisms.
