Ubuntu 22.04 LTS / 23.04 : libvirt vulnerabilities (USN-6126-1)

medium Nessus Plugin ID 176534

Language:

Synopsis

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

Description

The remote Ubuntu 22.04 LTS / 23.04 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6126-1 advisory.

 It was discovered that libvirt incorrectly handled the nwfilter driver. A local attacker could possibly use this issue to cause libvirt to crash, resulting in a denial of service. This issue only affected Ubuntu 22.04 LTS. (CVE-2022-0897)

 It was discovered that libvirt incorrectly handled queries for the SR-IOV PCI device capabilities. A local attacker could possibly use this issue to cause libvirt to consume resources, leading to a denial of service. (CVE-2023-2700)

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.
