medium Nessus Plugin ID 301155

Language:

Synopsis

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

Description

The remote Ubuntu 22.04 LTS / 24.04 LTS / 25.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-8073-1 advisory.

 It was discovered that the UHCI controller implementation of QEMU could be brought into an invalid state.
 An attacker inside the guest could possibly use this issue to cause QEMU to crash, resulting in a denial of service. (CVE-2024-8354)

 It was discovered that QEMU incorrectly handled memory during certain VNC operations. An remote attacker could possibly use this issue to cause QEMU to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2025-11234)

 It was discovered that the e1000 network device implementation of QEMU could be made to write out of bounds. An attacker inside the guest could possibly use this issue to cause QEMU to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 24.04 LTS and Ubuntu 25.10. (CVE-2025-12464)

 It was discovered that the virtio-crypto device implementation of QEMU did not limit the length of a certain path input. An attacker inside the guest could possibly use this issue to cause QEMU to consume large amount of memory, resulting in a denial of service. This issue only affected Ubuntu 24.04 LTS and Ubuntu 25.10. (CVE-2025-14876)

 It was discovered that the KVM Xen guest support of QEMU could be made to read out of bounds. An attacker inside the guest could possibly use this issue to cause QEMU to crash, resulting in a denial of service.
 This issue only affected Ubuntu 24.04 LTS and Ubuntu 25.10. (CVE-2026-0665)

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.
