Synopsis

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

Description

The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 LTS / 22.04 LTS / 23.04 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6167-1 advisory.

 It was discovered that QEMU did not properly manage the guest drivers when shared buffers are not allocated. A malicious guest driver could use this issue to cause QEMU to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 20.04 LTS, Ubuntu 22.04 LTS and Ubuntu 22.10. (CVE-2022-1050)

 It was discovered that QEMU did not properly check the size of the structure pointed to by the guest physical address pqxl. A malicious guest attacker could use this issue to cause QEMU to crash, resulting in a denial of service. This issue only affected Ubuntu 14.04 LTS, Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, Ubuntu 22.04 LTS and Ubuntu 22.10. (CVE-2022-4144)

 It was discovered that QEMU did not properly manage memory in the ACPI Error Record Serialization Table (ERST) device. A malicious guest attacker could use this issue to cause QEMU to crash, resulting in a denial of service. This issue only affected Ubuntu 22.10. (CVE-2022-4172)

 It was discovered that QEMU did not properly manage memory when DMA memory writes happen repeatedly in the lsi53c895a device. A malicious guest attacker could use this issue to cause QEMU to crash, resulting in a denial of service. (CVE-2023-0330)

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.
