"The remote NewStart CGSL host, running version MAIN 7.02, has vim packages installed that are affected by multiple
vulnerabilities:

  - Vim before 9.0.2142 has a stack-based buffer overflow because did_set_langmap in map.c calls sprintf to
    write to the error buffer that is passed down to the option callback functions. (CVE-2024-22667)

  - Vim is an improved version of the good old UNIX editor Vi. Heap-use-after-free in memory allocated in the
    function `ga_grow_inner` in in the file `src/alloc.c` at line 748, which is freed in the file
    `src/ex_docmd.c` in the function `do_cmdline` at line 1010 and then used again in `src/cmdhist.c` at line
    759. When using the `:history` command, it's possible that the provided argument overflows the accepted
    value. Causing an Integer Overflow and potentially later an use-after-free. This vulnerability has been
    patched in version 9.0.2068. (CVE-2023-46246)

  - Use After Free in GitHub repository vim/vim prior to 9.0.1840. (CVE-2023-4733)

  - Integer Overflow or Wraparound in GitHub repository vim/vim prior to 9.0.1846. (CVE-2023-4734)

  - Out-of-bounds Write in GitHub repository vim/vim prior to 9.0.1847. (CVE-2023-4735)

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