Ubuntu 22.04 LTS / 24.04 LTS / 25.04 : QEMU vulnerabilities (USN-7744-1)

medium Nessus Plugin ID 265091

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 22.04 LTS / 24.04 LTS / 25.04 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7744-1 advisory.

 It was discovered that QEMU incorrectly handled certain virtio devices. A privileged guest attacker could use this issue to cause QEMU to crash, leading to a denial of service, or possibly execute arbitrary code.
 This issue only affected Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. (CVE-2024-3446)

 It was discovered that QEMU incorrectly handled SDHCI device emulation. A guest attacker could possibly use this issue to cause QEMU to crash, leading to a denial of service. This issue only affected Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. (CVE-2024-3447)

 It was discovered that QEMU incorrectly handled calculating the checksum of a short-sized fragmented packet. A guest attacker could possibly use this issue to cause QEMU to crash, leading to a denial of service. This issue only affected Ubuntu 24.04 LTS. (CVE-2024-3567)

 It was discovered that the QEMU qemu-img utility incorrectly handled certain crafted image files. An attacker could use this issue to cause QEMU to consume resources, leading to a denial of service, or possibly read and write to an existing external file. This issue only affected Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. (CVE-2024-4467)

 It was discovered that QEMU incorrectly handled the RSS feature on virtio-net devices. A privileged guest attacker could possibly use this issue to cause QEMU to crash, leading to a denial of service. This issue only affected Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. (CVE-2024-6505)

 It was discovered that QEMU incorrectly handled the NBD server. An attacker could use this issue to cause QEMU to consume resources, leading to a denial of service. This issue only affected Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. (CVE-2024-7409)

 It was discovered that QEMU incorrectly handled certain USB devices. A guest attacker could possibly use this issue to cause QEMU to crash, leading to a denial of service. This issue only affected Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. (CVE-2024-8354)

 It was discovered that the QEMU package incorrectly set up a binfmt_misc registration with the C (Credential) flag. A local attacker could use this with a suid/sgid binary to escalate privileges. This update will no longer run foreign-architecture binaries with suid/sgid with elevated privileges.

Tenable has extracted the preceding description block directly from the Ubuntu 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 packages.
