Ubuntu 22.04 LTS / 24.04 LTS / 25.10 : Nova vulnerability (USN-8049-1)

high Nessus Plugin ID 299492

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 22.04 LTS / 24.04 LTS / 25.10 host has packages installed that are affected by a vulnerability as referenced in the USN-8049-1 advisory.

 Dan Smith discovered that Nova incorrectly called qemu-img without a format restriction when resizing disks. An attacker could possibly use this issue to destroy data on the host system.

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.

Solution

Update the affected packages.
