"The version of Vim installed on the remote host is prior to 9.1.1097. It is, therefore, affected by a vulnerability as
referenced in the 9_1_1097 advisory.

  - A vulnerability classified as problematic was found in vim up to 9.1.1096. This vulnerability affects
    unknown code of the file src/main.c. The manipulation of the argument --log leads to memory corruption. It
    is possible to launch the attack on the local host. Upgrading to version 9.1.1097 is able to address this
    issue. The patch is identified as c5654b84480822817bb7b69ebc97c174c91185e9. It is recommended to upgrade
    the affected component. (CVE-2025-1215)

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