		<Note Title="Description" Type="General" Ordinal="3" xml:lang="en">QEMU is a FAST! processor emulator using dynamic translation to achieve good emulation speed.

	QEMU has two operating modes:

		Full system emulation. In this mode, QEMU emulates a full system (for example a PC),
		including one or several processors and various peripherals. It can be used to launch
		different Operating Systems without rebooting the PC or to debug system code.

		User mode emulation. In this mode, QEMU can launch processes compiled for one CPU on another CPU.
		It can be used to launch the Wine Windows API emulator (https://www.winehq.org) or to ease
		cross-compilation and cross-debugging.
		You can refer to https://www.qemu.org for more infortmation.

Security Fix(es):

An integer underflow issue was found in the QEMU VNC server while processing ClientCutText messages in the extended format. A malicious client could use this flaw to make QEMU unresponsive by sending a specially crafted payload message, resulting in a denial of service.(CVE-2022-3165)</Note>
		<Note Title="Topic" Type="General" Ordinal="4" xml:lang="en">An update for qemu is now available for openEuler-22.03-LTS.

openEuler Security has rated this update as having a security impact of medium. A Common Vunlnerability Scoring System(CVSS)base score,which gives a detailed severity rating, is available for each vulnerability from the CVElink(s) in the References section.</Note>
