high Nessus Plugin ID 180438

Language:

Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 38 host has packages installed that are affected by multiple vulnerabilities as referenced in the FEDORA-2023-6a87c003c4 advisory.

 - In Mosquitto before 2.0.16, excessive memory is allocated based on malicious initial packets that are not CONNECT packets. (CVE-2023-0809)

 - In Mosquitto before 2.0.16, a memory leak occurs when clients send v5 CONNECT packets with a will message that contains invalid property types. (CVE-2023-3592)

 - The broker in Eclipse Mosquitto 1.3.2 through 2.x before 2.0.16 has a memory leak that can be abused remotely when a client sends many QoS 2 messages with duplicate message IDs, and fails to respond to PUBREC commands. This occurs because of mishandling of EAGAIN from the libc send function.
 (CVE-2023-28366)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected libwebsockets and / or mosquitto packages.
