EulerOS Virtualization 2.12.1 : qemu (EulerOS-SA-2024-2321)

high Nessus Plugin ID 206526

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

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

A heap based buffer overflow was found in the SDHCI device emulation of QEMU. The bug is triggered when both `s-data_count` and the size of `s-fifo_buffer` are set to 0x200, leading to an out-of-bound access. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition.(CVE-2024-3447)

A double free vulnerability was found in QEMU virtio devices (virtio-gpu, virtio-serial-bus, virtio- crypto), where the mem_reentrancy_guard flag insufficiently protects against DMA reentrancy issues. This issue could allow a malicious privileged guest user to crash the QEMU process on the host, resulting in a denial of service or allow arbitrary code execution within the context of the QEMU process on the host.(CVE-2024-3446)

Tenable has extracted the preceding description block directly from the EulerOS Virtualization qemu security advisory.

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

Solution

Update the affected qemu packages.
