Doc Text:
A flaw was found in the Qt SVG module. A remote attacker could trigger this issue by providing a specially crafted SVG (Scalable Vector Graphics) file containing deeply nested elements. When parsed, this leads to uncontrolled recursion and stack exhaustion, resulting in an application crash and a Denial of Service (DoS).
