Alpine: multiple qemu packages: security update to 5.2.0-r0

high Tenable Self-Hosted Container Security Plugin ID 406789

Description

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)
