CVSS: 7.5EPSS: 0%CPEs: 1EXPL: 0CVE-2023-28366 – mosquitto: memory leak leads to unresponsive broker
https://notcve.org/view.php?id=CVE-2023-28366
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. El intermediario en Eclipse Mosquitto 1.3.2 hasta 2.x anterior a 2.0.16 tiene una pérdida de memoria de la que se puede abusar de forma remota cuando un cliente envía muchos mensajes QoS 2 con ID de mensajes duplicados y no responde a los comandos PUBREC. Esto ocurre debido a un mal manejo de EAGAIN desde la función de envío de libc. A memory leak vulnerability was found in Eclipse Mosquitto. • https://github.com/eclipse/mosquitto/commit/6113eac95a9df634fbc858be542c4a0456bfe7b9 https://github.com/eclipse/mosquitto/compare/v2.0.15...v2.0.16 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/KJ2FMBGVVQEQWTTQB7YLKTAHMX2UM66X https://mosquitto.org/blog/2023/08/version-2-0-16-released https://security.gentoo.org/glsa/202401-09 https://www.compass-security.com/fileadmin/Research/Advisories/2023_02_CSNC-2023-001_Eclipse_Mosquitto_Memory_Leak.txt https://www.debian&# • CWE-401: Missing Release of Memory after Effective Lifetime •
