Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Memory leak

EUVDB-ID: #VU79936

Risk: Medium

CVSSv4.0: 4.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2023-28366

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

Exploit availability: No

Description

The vulnerability allows a remote user to perform DoS attack on the target system.

The vulnerability exists due memory leak in broker. A remote client can send multiple QoS 2 messages with the same message ID, but then never respond to the PUBREC commands, which results in memory leak and denial of service condition.

Mitigation

Install update from vendor's website.
