The Rocky Linux 9.6 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.6:CLSA-2026:1791540596 advisory.

  - ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to     versions 7.1.2-15 and 6.9.13-40, ImageMagick's path security policy is enforced on the raw filename string     before the filesystem resolves it. As a result, a policy rule such as /etc/* can be bypassed by a path     traversal. The OS resolves the traversal and opens the sensitive file, but the policy matcher only sees     the unnormalized path and therefore allows the read. This enables local file disclosure (LFI) even when     policy-secure.xml is applied. Actions to prevent reading from files have been taken in versions .7.1.2-15     and 6.9.13-40 But it make sure writing is also not possible the following should be added to one's policy.
    This will also be included in ImageMagick's more secure policies by default. (CVE-2026-25965)

  - ImageMagick before 7.1.2-30 and 6.9.13-55 fails to properly lower the memory budget when an operation     inside OpenPixelCache fails. Repeated triggering of such failures can exhaust the process memory budget     and result in a denial of service. (CVE-2026-86420)

  - ImageMagick before 7.1.2-30 and 6.9.13-55 contains a memory leak in the MSL image decoder. A crafted MSL     image triggers memory allocation without proper deallocation, allowing an attacker to exhaust memory and     cause a denial of service. (CVE-2026-86421)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
