[ Reason ]
A bug in plasma-discover causes a Denial of Service attack
against the KDE servers. 3 packages needs to be patch to
mitigate the attack: knewstuff, plasma-desktop and
plasma-discover.
This update fixes bug #1006126 for bullseye and has been
fixed in unstable in version 5.90.0-1 for knewstuff.
[ Impact ]
Running the old version causes considerable load for the KDE
servers.
[ Tests ]
No manual tests have been performed.
[ Risks ]
The risks are rather low as the update is a single patch.
The patch has been created by KDE upstream specifically for the
version in bullseye.
[ Checklist ]
[x] *all* changes are documented in the d/changelog
[x] I reviewed all changes and I approve them
[x] attach debdiff against the package in (old)stable
[x] the issue is verified as fixed in unstable
[ Changes ]
The update contains a single patch to help ease the load on
KDE servers.
[ Other info ]
It would be good if users of KDE plasma could receive the update
as quick as possible.
