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.

The remote SUSE Linux SLES11 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:14704-1 advisory.

  - 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)

  - The VNC websocket frame decoder in QEMU allows remote attackers to cause a denial of service (memory and     CPU consumption) via a large (1) websocket payload or (2) HTTP headers section. (CVE-2015-1779)

  - 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)

  - In QEMU 5.0.0 and earlier, es1370_transfer_audio in hw/audio/es1370.c does not properly validate the frame     count, which allows guest OS users to trigger an out-of-bounds access during an es1370_write() operation.
    (CVE-2020-13361)

  - In QEMU 5.0.0 and earlier, megasas_lookup_frame in hw/scsi/megasas.c has an out-of-bounds read via a     crafted reply_queue_head field from a guest OS user. (CVE-2020-13362)

  - rom_copy() in hw/core/loader.c in QEMU 4.0 and 4.1.0 does not validate the relationship between two     addresses, which allows attackers to trigger an invalid memory copy operation. (CVE-2020-13765)

  - 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)

  - QEMU 5.0.0 has a use-after-free in hw/usb/hcd-xhci.c because the usb_packet_map return value is not     checked. (CVE-2020-25084)

  - 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)

  - 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)

  - 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)

  - ide_atapi_cmd_reply_end in hw/ide/atapi.c in QEMU 5.1.0 allows out-of-bounds read access because a buffer     index is not validated. (CVE-2020-29443)

  - A race condition flaw was found in the 9pfs server implementation of QEMU up to and including 5.2.0. This     flaw allows a malicious 9p client to cause a use-after-free error, potentially escalating their privileges     on the system. The highest threat from this vulnerability is to confidentiality, integrity as well as     system availability. (CVE-2021-20181)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

According to the versions of the qemu-kvm package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - 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-2020-1586     3)

  - 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)

Updated qemu packages fix multiple security vulnerabilities :

Sibiao Luo discovered that QEMU incorrectly handled device hot-unplugging. A local user could possibly use this flaw to cause a denial of service (CVE-2013-4377).

Michael S. Tsirkin discovered that QEMU incorrectly handled vmxnet3 devices. A local guest could possibly use this issue to cause a denial of service, or possibly execute arbitrary code on the host (CVE-2013-4544).

Multiple integer overflow, input validation, logic error, and buffer overflow flaws were discovered in various QEMU block drivers. An attacker able to modify a disk image file loaded by a guest could use these flaws to crash the guest, or corrupt QEMU process memory on the host, potentially resulting in arbitrary code execution on the host with the privileges of the QEMU process (CVE-2014-0143, CVE-2014-0144, CVE-2014-0145, CVE-2014-0147).

A buffer overflow flaw was found in the way the virtio_net_handle_mac() function of QEMU processed guest requests to update the table of MAC addresses. A privileged guest user could use this flaw to corrupt QEMU process memory on the host, potentially resulting in arbitrary code execution on the host with the privileges of the QEMU process (CVE-2014-0150).

A divide-by-zero flaw was found in the seek_to_sector() function of the parallels block driver in QEMU. An attacker able to modify a disk image file loaded by a guest could use this flaw to crash the guest (CVE-2014-0142).

A NULL pointer dereference flaw was found in the QCOW2 block driver in QEMU. An attacker able to modify a disk image file loaded by a guest could use this flaw to crash the guest (CVE-2014-0146).

It was found that the block driver for Hyper-V VHDX images did not correctly calculate BAT (Block Allocation Table) entries due to a missing bounds check. An attacker able to modify a disk image file loaded by a guest could use this flaw to crash the guest (CVE-2014-0148).

An out-of-bounds memory access flaw was found in the way QEMU's IDE device driver handled the execution of SMART EXECUTE OFFLINE commands.
A privileged guest user could use this flaw to corrupt QEMU process memory on the host, which could potentially result in arbitrary code execution on the host with the privileges of the QEMU process (CVE-2014-2894).

Two integer overflow flaws were found in the QEMU block driver for QCOW version 1 disk images. A user able to alter the QEMU disk image files loaded by a guest could use either of these flaws to corrupt QEMU process memory on the host, which could potentially result in arbitrary code execution on the host with the privileges of the QEMU process (CVE-2014-0222, CVE-2014-0223).

Multiple buffer overflow, input validation, and out-of-bounds write flaws were found in the way the virtio, virtio-net, virtio-scsi, and usb drivers of QEMU handled state loading after migration.
