 Hi,

 every application based on Qt will crash when opening a crafted plain

 Thank you and have a nice weekend.

Let me forward you a question I got on the bug:

https://bugs.launchpad.net/ubuntu/+source/qtbase-opensource-src/+bug/1848784/comments/1

  This would appear to have security implications since I imagine if an email
  were sent to a KMail recipient which was crafted in this same way it would
  crash KMail? If this is likely true a CVE should be requested from MITRE via
  https://cveform.mitre.org/ so that other distros etc can ensure they ship
  this patch too.

What do you think about this?
