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. This issue has been addressed in commit cb0b99f0 which has been included in release version 9.0.2107. Users are advised to upgrade. There are no known workarounds for this vulnerability.
