Package : dino-im
CVE ID : CVE-2023-28686
Debian Bug : 1033370

Kim Alvefur discovered that insufficient message sender validation in
dino-im, a modern XMPP/Jabber client, may result in manipulation of
entries in the personal bookmark store without user interaction via a
specially crafted message. Additionally an attacker can take advantage
of this flaw to change how group chats are displayed or force a user to
join or leave an attacker-selected groupchat.

For the stable distribution (bullseye), this problem has been fixed in
version 0.2.0-3+deb11u1.

We recommend that you upgrade your dino-im packages.
