Vulnerabilities 2
-
High 7.1
Uncontrolled recursion in QDomDocument/QDomNode serialization causes stack exhaustion (QtXml)
Uncontrolled recursion (CWE-674) in the QDomDocument/QDomNode serialization path of the Qt XML module (QtXml, qtbase). QDomElementPrivate::save() and QDomNodePrivate::save() recurse mutually, consuming one stack frame per level of element nesting with no dept…

High 7.1
Unbounded recursion vulnerability in the QDomNode destructor of Qt XML impacts Qt
QDomDocument XML parsing is vulnerable to a remotely-triggerable denial-of-service crash when processing untrusted input.
