Test ID: | 1.3.6.1.4.1.25623.1.1.2.2021.1667 |
Category: | Huawei EulerOS Local Security Checks |
Title: | Huawei EulerOS: Security Advisory for qemu (EulerOS-SA-2021-1667) |
Summary: | The remote host is missing an update for the Huawei EulerOS 'qemu' package(s) announced via the EulerOS-SA-2021-1667 advisory. |
Description: | Summary: The remote host is missing an update for the Huawei EulerOS 'qemu' package(s) announced via the EulerOS-SA-2021-1667 advisory. Vulnerability Insight: In QEMU through 5.0.0, an integer overflow was found in the SM501 display driver implementation. This flaw occurs in the COPY_AREA macro while handling MMIO write operations through the sm501_2d_engine_write() callback. A local attacker could abuse this flaw to crash the QEMU process in sm501_2d_operation() in hw/display/sm501.c on the host, resulting in a denial of service.(CVE-2020-12829) slirp.c in libslirp through 4.3.1 has a buffer over-read because it tries to read a certain amount of header data even if that exceeds the total packet length.(CVE-2020-29130) ncsi.c in libslirp through 4.3.1 has a buffer over-read because it tries to read a certain amount of header data even if that exceeds the total packet length.(CVE-2020-29129) hw/net/e1000e_core.c in QEMU 5.0.0 has an infinite loop via an RX descriptor with a NULL buffer address.(CVE-2020-28916) ati_2d_blt in hw/display/ati_2d.c in QEMU 4.2.1 can encounter an outside-limits situation in a calculation. A guest can crash the QEMU process.(CVE-2020-27616) eth_get_gso_type in net/eth.c in QEMU 4.2.1 allows guest OS users to trigger an assertion failure. A guest can crash the QEMU process via packet data that lacks a valid Layer 3 protocol.(CVE-2020-27617) A reachable assertion issue was found in the USB EHCI emulation code of QEMU. It could occur while processing USB requests due to missing handling of DMA memory map failure. A malicious privileged user within the guest may abuse this flaw to send bogus USB requests and crash the QEMU process on the host, resulting in a denial of service.(CVE-2020-25723) hw/usb/hcd-ohci.c in QEMU 5.0.0 has a stack-based buffer over-read via values obtained from the host controller driver.(CVE-2020-25624) hw/usb/hcd-ohci.c in QEMU 5.0.0 has an infinite loop when a TD list has a loop.(CVE-2020-25625) In libslirp 4.1.0, as used in QEMU 4.2.0, tcp_subr.c misuses snprintf return values, leading to a buffer overflow in later code.(CVE-2020-8608) tcp_emu in tcp_subr.c in libslirp 4.1.0, as used in QEMU 4.2.0, mismanages memory, as demonstrated by IRC DCC commands in EMU_IRC. This can cause a heap-based buffer overflow or other out-of-bounds access which can lead to a DoS or potential execute arbitrary code.(CVE-2020-7039) ip_reass in ip_input.c in libslirp 4.0.0 has a heap-based buffer overflow via a large packet because it mishandles a case involving the first fragment.(CVE-2019-14378) A flaw was found in the memory management API of QEMU during the initialization of a memory region cache. This issue could lead to an out-of-bounds write access to the MSI-X table while performing MMIO operations. A guest user may abuse this flaw to crash the QEMU process on the host, resulting in a denial of service. This flaw affects QEMU versions prior to 5.2.0.(CVE-2020-27821) QEMU: reachable assertion failure in net_tx_pkt_add_raw_fragment() in hw/net/net_tx_pkt.c ... [Please see the references for more information on the vulnerabilities] Affected Software/OS: 'qemu' package(s) on Huawei EulerOS Virtualization release 2.9.0. Solution: Please install the updated package(s). CVSS Score: 6.8 CVSS Vector: AV:N/AC:M/Au:N/C:P/I:P/A:P |
