The flaw arises when internal attribute metadata (atype) is modified by libxslt's xsltSetSourceNodeFlags() function during processing of result tree fragments. If the flag corruption prevents proper removal of ID references, later memory cleanup routines may operate on already-freed memory. Since libxslt is commonly used in server-side XML processing, this could result in denial-of-service or potentially facilitate code execution under certain memory reuse conditions.", "threat_severity": "Important"}
