Description Alexander Bergmann 2018-12-06 08:38:08 UTC 
CVE-2018-15518, Qt Base: “double free or corruption” in QXmlStreamReader

Fix possible heap corruption in QXmlStream

The value of 'tos' at the check might already be on the last element,
so triggering stack expansion on the second last element is too late.
