The version of vim installed on the remote host is prior to 9.0.1034. It is, therefore, affected by multiple vulnerabilities as referenced in the SSA:2022-342-02 advisory.

  • Heap-based Buffer Overflow in GitHub repository vim/vim prior to 9.0.0742. (CVE-2022-3491)

  • Heap-based Buffer Overflow in GitHub repository vim/vim prior to 9.0.0765. (CVE-2022-3520)

  • Use After Free in GitHub repository vim/vim prior to 9.0.0789. (CVE-2022-3591)

  • Heap based buffer overflow in vim/vim 9.0.0946 and below by allowing an attacker to CTRL-W gf in the expression used in the RHS of the substitute command. (CVE-2022-4141)

  • Use After Free in GitHub repository vim/vim prior to 9.0.0882. (CVE-2022-4292)

  • Floating Point Comparison with Incorrect Operator in GitHub repository vim/vim prior to 9.0.0804.
    (CVE-2022-4293)

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