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.

The remote Oracle Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2024-12605 advisory.

  - 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)

  - A flaw was found in the QEMU virtual crypto device while handling data encryption/decryption requests in     virtio_crypto_handle_sym_req. There is no check for the value of `src_len` and `dst_len` in     virtio_crypto_sym_op_helper, potentially leading to a heap buffer overflow when the two values differ.
    (CVE-2023-3180)

  - A flaw was found in the QEMU built-in VNC server. When a client connects to the VNC server, QEMU checks     whether the current number of connections crosses a certain threshold and if so, cleans up the previous     connection. If the previous connection happens to be in the handshake phase and fails, QEMU cleans up the     connection again, resulting in a NULL pointer dereference issue. This could allow a remote unauthenticated     client to cause a denial of service. (CVE-2023-3354)

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)

  - A DMA reentrancy issue was found in the USB EHCI controller emulation of QEMU. EHCI does not verify if the     Buffer Pointer overlaps with its MMIO region when it transfers the USB packets. Crafted content may be     written to the controller's registers and trigger undesirable actions (such as reset) while the device is     still transferring packets. This can ultimately lead to a use-after-free issue. A malicious guest could     use this flaw to crash the QEMU process on the host, resulting in a denial of service condition, or     potentially execute arbitrary code within the context of the QEMU process on the host. This flaw affects     QEMU versions before 7.0.0. (CVE-2021-3750)

  - A vulnerability in the lsi53c895a device affects the latest version of qemu. A DMA-MMIO reentrancy problem     may lead to memory corruption bugs like stack overflow or use-after-free. (CVE-2023-0330)

This flaw affects     QEMU versions before 7.0.0. (CVE-2021-3750)

  - A DMA reentrancy issue was found in the NVM Express Controller (NVME) emulation in QEMU. This CVE is     similar to CVE-2021-3750 and, just like it, when the reentrancy write triggers the reset function     nvme_ctrl_reset(), data structs will be freed leading to a use-after-free issue. A malicious guest could     use this flaw to crash the QEMU process on the host, resulting in a denial of service condition or,     potentially, executing arbitrary code within the context of the QEMU process on the host. (CVE-2021-3929)

  - A flaw was found in the QEMU implementation of VMWare's paravirtual RDMA device. This flaw allows a     crafted guest driver to execute HW commands when shared buffers are not yet allocated, potentially leading     to a use-after-free condition. (CVE-2022-1050)

  - A flaw was found in the vhost-vsock device of QEMU. In case of error, an invalid element was not detached     from the virtqueue before freeing its memory, leading to memory leakage and other unexpected results.
    Affected QEMU versions <= 6.2.0. (CVE-2022-26354)

  - A vulnerability in the lsi53c895a device affects the latest version of qemu. A DMA-MMIO reentrancy problem     may lead to memory corruption bugs like stack overflow or use-after-free. (CVE-2023-0330)

  - A potential stack overflow via infinite loop issue was found in various NIC emulators of QEMU in versions     up to and including 5.2.0. The issue occurs in loopback mode of a NIC wherein reentrant DMA checks get     bypassed. A guest user/process may use this flaw to consume CPU cycles or crash the QEMU process on the     host resulting in DoS scenario. (CVE-2021-3416) (CVE-2023-2861)

  - A flaw was found in the QEMU virtual crypto device while handling data encryption/decryption requests in     virtio_crypto_handle_sym_req. There is no check for the value of `src_len` and `dst_len` in     virtio_crypto_sym_op_helper, potentially leading to a heap buffer overflow when the two values differ.

The qxl_phys2virt()     function does not check the size of the structure pointed to by the guest physical address, potentially     reading past the end of the bar space into adjacent pages. A malicious guest user could use this flaw to     crash the QEMU process on the host causing a denial of service condition. (CVE-2022-4144)

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

According to the versions of the qemu packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - 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)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote Debian 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-4980 advisory.

  - Several memory leaks were found in the virtio vhost-user GPU device (vhost-user-gpu) of QEMU in versions     up to and including 6.0. They exist in contrib/vhost-user-gpu/vhost-user-gpu.c and contrib/vhost-user-     gpu/virgl.c due to improper release of memory (i.e., free) after effective lifetime. (CVE-2021-3544)

  - An information disclosure vulnerability was found in the virtio vhost-user GPU device (vhost-user-gpu) of     QEMU in versions up to and including 6.0. The flaw exists in virgl_cmd_get_capset_info() in contrib/vhost-     user-gpu/virgl.c and could occur due to the read of uninitialized memory. A malicious guest could exploit     this issue to leak memory from the host. (CVE-2021-3545)

  - A flaw was found in vhost-user-gpu of QEMU in versions up to and including 6.0. An out-of-bounds write     vulnerability can allow a malicious guest to crash the QEMU process on the host resulting in a denial of     service or potentially execute arbitrary code on the host with the privileges of the QEMU process. The     highest threat from this vulnerability is to data confidentiality and integrity as well as system     availability. (CVE-2021-3546)

  - A flaw was found in the USB redirector device emulation of QEMU in versions prior to 6.1.0-rc2. It occurs     when dropping packets during a bulk transfer from a SPICE client due to the packet queue being full. A     malicious SPICE client could use this flaw to make QEMU call free() with faked heap chunk metadata,     resulting in a crash of QEMU or potential code execution with the privileges of the QEMU process on the     host. (CVE-2021-3682)

  - An out-of-bounds write flaw was found in the UAS (USB Attached SCSI) device emulation of QEMU in versions     prior to 6.2.0-rc0. The device uses the guest supplied stream number unchecked, which can lead to out-of-     bounds access to the UASDevice->data3 and UASDevice->status3 fields. A malicious guest user could use this     flaw to crash QEMU or potentially achieve code execution with the privileges of the QEMU process on the     host. (CVE-2021-3713)

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