Kopete: CVE 2017-5593 (User Impersonation Vulnerability)

[Pali Rohár]

Hello!

I need to inform you that jabber protocol in Kopete is vulnerable to 
CVE-2017-5593 (User Impersonation Vulnerability) due to defect in 
underlying Psi xmpp library libiris -- which is part of Kopete source 
tree. Note that Kopete is vulnerable even it does not support XEP-0280: 
Message Carbons yet (because defect is in libiris).

All Kopete versions which are part of KDE 16.11.80 (and new) are 
affected.

Backported fix for libiris is now in Application/16.12 branch in commit 
https://commits.kde.org/kopete/6243764c4fd0985320d4a10b48051cc418d584ad

And so fix will be part of KDE 16.12.3 (Kopete 1.11.3).
