Description SMASH SMASH 2023-10-19 07:35:58 UTC

In Eclipse Mosquito before and including 2.0.5, establishing a connection to the mosquitto server without sending data causes the EPOLLOUT event to be added, which results excessive CPU consumption. This could be used by a malicious actor to perform denial of service type attack. This issue is fixed in 2.0.6

We are on 2.0.15 in Factory, and 2.0.10 in backports. Nothing to do, closing.
