Alpine: multiple mosquitto packages: security update to 2.0.16-r0
high Tenable Cloud Security Plugin ID 424164
Description
There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:- 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.
