Описание
In sol commit 373d848 (2024-12-12), the broker does not fully release resources when handling malformed or duplicate CONNECT packets. When clients send invalid CONNECT packets - either due to repeated attempts or failed authentication - the server may silently drop the connection or send a CONNACK but fail to close the session or deallocate internal resources. This behavior allows an attacker to create numerous half-open connections that consume memory and file descriptors indefinitely, potentially triggering the Linux OOM killer and causing a denial of service.
A flaw was found in sol. The broker does not fully release resources when handling malformed or duplicate CONNECT packets. A remote attacker can send invalid CONNECT packets, which may cause the server to silently drop the connection or send a CONNACK without properly closing the session or deallocating internal resources. This behavior allows an attacker to create numerous half-open connections, consuming memory and file descriptors indefinitely, potentially leading to a denial of service.
