The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - A flaw has been found in LibTIFF 4.7.0. This affects the function
    _TIFFmallocExt/_TIFFCheckRealloc/TIFFHashSetNew/InitCCITTFax3 of the file tools/tiffcmp.c of the component     tiffcmp. Executing manipulation can lead to memory leak. The attack is restricted to local execution. This     attack is characterized by high complexity. It is indicated that the exploitability is difficult. The     exploit has been published and may be used. There is ongoing doubt regarding the real existence of this     vulnerability. This patch is called ed141286a37f6e5ddafb5069347ff5d587e7a4e0. It is best practice to apply     a patch to resolve this issue. A researcher disputes the security impact of this issue, because this is a     memory leak on a command line tool that is about to exit anyway. In the reply the project maintainer     declares this issue as a simple 'bug' when leaving the command line tool and (...) not a security issue     at all. (CVE-2025-9165)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Fedora 43 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2025-ebff4d54bf advisory.
