Vulnerability in Vim (CVE-2023-48232)
Summary
Vulnerability in Vim (CVE-2023-48232). Risk of unauthorized operations or information disclosure. Exploitable via cb0b99f0.
Original description
The description as published by the source.
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.
