There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - A flaw was found in qemu. A host privilege escalation issue was found in the virtio-fs shared file system
    daemon where a privileged guest user is able to create a device special file in the shared directory and
    use it to r/w access host devices. (CVE-2020-35517)

  - An issue was discovered in QEMU through 5.1.0. An out-of-bounds memory access was found in the ATI VGA
    device implementation. This flaw occurs in the ati_2d_blt() routine in hw/display/ati_2d.c while handling
    MMIO write operations through the ati_mm_write() callback. A malicious guest could use this flaw to crash
    the QEMU process on the host, resulting in a denial of service. (CVE-2020-24352)

  - 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)

  - pci_change_irq_level in hw/pci/pci.c in QEMU before 5.1.1 has a NULL pointer dereference because
    pci_get_bus() might not return a valid pointer. (CVE-2020-25742)

  - hw/ide/pci.c in QEMU before 5.1.1 can trigger a NULL pointer dereference because it lacks a pointer check
    before an ide_cancel_dma_sync call. (CVE-2020-25743)

This update for qemu fixes the following issues :

  - CVE-2020-14364: Fixed an OOB access while processing USB     packets (bsc#1175441,bsc#1176494).

  - CVE-2020-16092: Fixed a denial of service in packet     processing of various emulated NICs (bsc#1174641).

  - CVE-2020-15863: Fixed a buffer overflow in the XGMAC     device (bsc#1174386).

  - CVE-2020-24352: Fixed an out-of-bounds read/write in     ati-vga device emulation in ati_2d_blt (bsc#1175370).

  - Allow to IPL secure guests with -no-reboot (bsc#1174863)
