<p>I'm not sure if it was necessary or not, but I killed all my
dnfdragora-updater processes and also commented out the contents
of /etc/xdg/autostart/org.mageia.dnfdragora-updater.desktop so

fixed (;-))</p></div></blockquote><div><br></div><div>I did </div><div><br></div><div>rpm -qa grub2-\* shim-\* --qf "%{SOURCERPM}\n" | sort | uniq</div><div><br></div><div>on my Fedora and got</div><div><br></div><div>grub2-2.02-109.fc31.src.rpm<br>shim-15-8.src.rpm<br></div><div><br></div><div>so my version is ok.</div></div></div></blockquote><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div class="gmail_quote"><div><br></div><div>It looks like this problem was caused by a patch which then allowed a malformed token to cause a buffer overflow.</div><div><br></div></div></div></blockquote><div><br></div><div>Sorry, not a patch but a native flaw in grub's handling of UEFI Secure Boot which is the BootHole.
