CVE-2023-48232: Floating point Exception in adjust_plines_for_skipcol()
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.

Severity: Low
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.
Impact is rather low, since we do not expect many users to have those non-default setting
set.
The Vim project would like to thank Fabian Toepfer for reporting this issue
which is now fixed in Vim patch 9.0.2107.
