Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.04 LTS / 24.10 : QEMU vulnerabilities (USN-7094-1)

medium Nessus Plugin ID 210736

Language:

Synopsis

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

Description

The remote Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.04 LTS / 24.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7094-1 advisory.

 It was discovered that QEMU incorrectly handled memory during certain VNC operations. A remote attacker could possibly use this issue to cause QEMU to consume resources, resulting in a denial of service. This issue only affected Ubuntu 14.04 LTS. (CVE-2019-20382)

 It was discovered that QEMU incorrectly handled certain memory copy operations when loading ROM contents.
 If a user were tricked into running an untrusted kernel image, a remote attacker could possibly use this issue to run arbitrary code. This issue only affected Ubuntu 14.04 LTS. (CVE-2020-13765)

 Aviv Sasson discovered that QEMU incorrectly handled Slirp networking. A remote attacker 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 14.04 LTS. (CVE-2020-1983)

 It was discovered that the SLiRP networking implementation of the QEMU emulator did not properly manage memory under certain circumstances. An attacker could use this to cause a heap-based buffer overflow or other out- of-bounds access, which can lead to a denial of service (application crash) or potential execute arbitrary code. This issue only affected Ubuntu 14.04 LTS. (CVE-2020-7039)

 It was discovered that the SLiRP networking implementation of the QEMU emulator misuses snprintf return values. An attacker could use this to cause a denial of service (application crash) or potentially execute arbitrary code. This issue only affected Ubuntu 14.04 LTS. (CVE-2020-8608)

 It was discovered that QEMU SLiRP networking incorrectly handled certain udp packets. An attacker inside a guest could possibly use this issue to leak sensitive information from the host. This issue only affected Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. (CVE-2021-3592, CVE-2021-3594)

 It was discovered that QEMU had a DMA reentrancy issue, leading to a use-after-free vulnerability. An attacker could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 18.04 LTS, Ubuntu 20.04 LTS and Ubuntu 22.04 LTS. (CVE-2023-3019)

 It was discovered that QEMU had a flaw in Virtio PCI Bindings, leading to a triggerable crash via vhost_net_stop. An attacker inside a guest could possibly use this issue to cause a denial of service.
 This issue only affected Ubuntu 24.04 LTS and Ubuntu 24.10. (CVE-2024-4693)

 It was discovered that QEMU incorrectly handled memory in virtio-sound, leading to a heap-based buffer overflow. An attacker could possibly use this issue to cause a denial of service or execute arbitrary code. This issue only affected Ubuntu 24.04 LTS and Ubuntu 24.10. (CVE-2024-7730)

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.
