"A segmentation fault was found in Vim before 9.1.1043. In silent Ex mode (-s -e), Vim typically doesn't show a screen
and just operates silently in batch mode. However, it is still possible to trigger the function that handles the scrolling
of a gui version of Vim by feeding some binary characters to Vim. The function that handles the scrolling however may
be triggering a redraw, which will access the ScreenLines pointer, even so this variable hasn't been allocated (since
there is no screen). This vulnerability is fixed in 9.1.1043.

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