From 5b9285c34731e67f9f1d61ec804740991f2a0380 Mon Sep 17 00:00:00 2001
From: Eirik Aavitsland <eirik.aavitsland@qt.io>
Date: Mon, 25 Oct 2021 14:17:55 +0200
Subject: [PATCH] Do stricter error checking when parsing path nodes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The SVG spec mandates that path parsing should terminate on the first
error encountered, and an error be reported. To improve the handling
of corrupt files, implement such error handling, and also limit the
number of QPainterPath elements to a reasonable range.
Fixes: QTBUG-96044
Pick-to: 6.2 5.15 5.12
Change-Id: Ic5e65d6b658516d6f1317c72de365c8c7ad81891
