"The remote Ubuntu 22.04 LTS / 24.04 LTS host has packages installed that are affected by a vulnerability as referenced
in the USN-6989-1 advisory.

    Dan Smith, Julia Kreger and Jay Faulkner discovered that in image processing for Ironic, a specially
    crafted image could be used by an authenticated user to exploit undesired behaviors in qemu-img, including
    possible unauthorized access to potentially sensitive data.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
