qemu security update
An update for qemu is now available for openEuler-20.03-LTS-SP3.
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 out-of-bounds memory access flaw was found in the ATI VGA device emulation of QEMU. This flaw occurs in the ati_2d_blt() routine while handling MMIO write operations when the guest provides invalid values for the destination display parameters. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service.(CVE-2021-3638)
An update for qemu is now available for openEuler-20.03-LTS-SP3.
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.
