An update for qemu is now available for openEuler-22.03-LTS Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2023-1736 Final 1.0 1.0 2023-10-13 Initial 2023-10-13 2023-10-13 openEuler SA Tool V1.0 2023-10-13 qemu security update An update for qemu is now available for openEuler-22.03-LTS. QEMU is a FAST! processor emulator using dynamic translation to achieve good emulation speed. Security Fix(es): 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.(CVE-2023-3354) An update for qemu is now available for openEuler-22.03-LTS. openEuler Security has rated this update as having a security impact of high.
