Floating point exception in Vim when calculating line offset for overlong lines with smooth scrolling and specific 'cpo' setting, causing crash.

Vulnerability

In Vim versions prior to 9.0.2107, a floating point exception can occur when calculating the line offset for overlong lines if smooth scrolling is enabled and the 'cpo' setting includes the 'n' flag. This happens when a window border is present and the wrapped line continues on the next physical line directly in the window border. Only users with non-default settings are affected [1].

Exploitation

An attacker needs to coerce a victim into opening a file with an overlong line that triggers the condition. No special network position is required; local file access is sufficient. The sequence involves the user opening the crafted file with the specific settings enabled, causing the floating point exception and crash [1].

Impact

The vulnerability results in a denial of service via crash. There is no evidence of code execution or information disclosure; the impact is limited to a crash [1].

Mitigation

Users should upgrade to Vim version 9.0.2107 or later, which includes the fix in commit cb0b99f0. There are no known workarounds [1].
