CVE-2023-3354

Опубликовано: 11 июл. 2023
Источник: ubuntu
Приоритет: low
EPSS Низкий
CVSS3: 7.5

Описание

A flaw was found in the QEMU built-in VNC server. When a client connects to the VNC server, QEMU checks whether the current number of connections crosses a certain threshold and if so, cleans up the previous connection. If the previous connection happens to be in the handshake phase and fails, QEMU cleans up the connection again, resulting in a NULL pointer dereference issue. This could allow a remote unauthenticated client to cause a denial of service.
