Category:Huawei EulerOS Local Security Checks
Title:Huawei EulerOS: Security Advisory for qemu-kvm (EulerOS-SA-2020-2392)

Description:Summary:
The remote host is missing an update for the Huawei EulerOS
'qemu-kvm' package(s) announced via the EulerOS-SA-2020-2392 advisory.

Vulnerability Insight:
QEMU 4.1.0 has a memory leak in zrle_compress_data in ui/vnc-enc-zrle.c during a VNC disconnect operation because libz is misused, resulting in a situation where memory allocated in deflateInit2 is not freed in deflateEnd.(CVE-2019-20382)

libslirp 4.0.0, as used in QEMU 4.1.0, has a use-after-free in ip_reass in ip_input.c.(CVE-2019-15890)

An out-of-bounds read/write access flaw was found in the USB emulator of the QEMU in versions before 5.2.0. This issue occurs while processing USB packets from a guest when USBDevice 'setup_len' exceeds its 'data_buf[4096]' in the do_token_in, do_token_out routines. This flaw allows a guest user to crash the QEMU process, resulting in a denial of service, or the potential execution of arbitrary code with the privileges of the QEMU process on the host.(CVE-2020-14364)

hw/net/xgmac.c in the XGMAC Ethernet controller in QEMU before 07-20-2020 has a buffer overflow. This occurs during packet transmission and affects the highbank and midway emulated machines. A guest user or process could use this flaw to crash the QEMU process on the host, resulting in a denial of service or potential privileged code execution. This was fixed in commit 5519724a13664b43e225ca05351c60b4468e4555.(CVE-2020-15863)

The vmware-vga driver (hw/display/vmware_vga.c) in QEMU allows local guest users to write to qemu memory locations and gain privileges via unspecified parameters related to rectangle handling.(CVE-2014-3689)

Affected Software/OS:
'qemu-kvm' package(s) on Huawei EulerOS V2.0SP2.

Solution:
Please install the updated package(s).
