"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.

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