Description Andrej Nemec 2017-02-10 09:49:05 UTC

An incorrect implementation of XEP-0280: Message Carbons[0] in psi-plus client allows a remote attacker to impersonate any user, including contacts, in the vulnerable application's display. This allows for various kinds of social engineering attacks.
