CVE-2023-48233: overflow with count for :s command
Vim is an open source command line text editor. If the count after the :s command is larger than what fits into a (signed) long variable, abort with e_value_too_large. Impact is low, user interaction is required and a crash may not even happen in all situations. This issue has been addressed in commit ac6378773 which has been included in release version 9.0.2108. Users are advised to upgrade. There are no known workarounds for this vulnerability.
