Doc Text:
A flaw was found in Vim, an open source command line text editor. A floating point exception may occur when calculating the line offset for overlong lines when smooth scrolling is enabled and the cpo-settings include the 'n' flag. This issue may occur when a window border is present and when the wrapped line continues on the next physical line directly in the window border because the 'cpo' setting includes the 'n' flag. Only users with non-default settings are affected and the exception should only result in a crash.

Description TEJ RATHI 2023-11-17 12:12:48 UTC 
Vim is an open source command line text editor. A floating point exception may occur when calculating the line offset for overlong lines and smooth scrolling is enabled and the cpo-settings include the 'n' flag. This may happen when a window border is present and when the wrapped line continues on the next physical line directly in the window border because the 'cpo' setting includes the 'n' flag. Only users with non-default settings are affected and the exception should only result in a crash. There are no known workarounds for this vulnerability.
