High

Base vector

AV:N/AC:L/Au:N/C:N/I:N/A:C

Name of the Vulnerable Software and Affected Versions Gajim versions 1.2.x through 1.3.2

Description The issue is related to insufficient input validation when checking message IDs in multi-user chat, specifically with the XEP-0308 Last Message Correction extension. This allows remote attackers to cause a denial of service (crash) via a crafted XMPP message where the message ID equals the correction ID.

Recommendations For Gajim versions 1.2.x through 1.3.2, update to version 1.3.3 or later to resolve the issue. As a temporary workaround, consider disabling the XEP-0308 Last Message Correction extension in multi-user chat until a patch is available.
