Amazon Linux 2 : qemu (ALAS-2024-2624)

high Nessus Plugin ID 206016

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of qemu installed on the remote host is prior to 3.1.0-8. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2024-2624 advisory.

QEMU: sdhci: heap buffer overflow in sdhci_write_dataport() (CVE-2024-3447)

A flaw was found in the QEMU disk image utility (qemu-img) 'info' command. A specially crafted image file containing a `json:{}` value describing block devices in QMP could cause the qemu-img process on the host to consume large amounts of memory or CPU time, leading to denial of service or read/write to an existing external file. (CVE-2024-4467)

Tenable has extracted the preceding description block directly from the tested product 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

Run 'yum update qemu' to update your system.
