Vulnerability in Vim (CVE-2023-48235)
Summary
Vulnerability in Vim (CVE-2023-48235). Risk of unauthorized operations or information disclosure.
Original description
The description as published by the source.
Vim is an open source command line text editor. When parsing relative ex addresses one may unintentionally cause an
overflow. Ironically this happens in the existing overflow check, because the line number becomes negative and LONG_MAX - lnum will cause the overflow. Impact is low, user interaction is required and a crash may not even happen in all situations. This issue has been addressed in commit 060623e which has been included in release version 9.0.2110. Users are advised to upgrade. There are no known workarounds for this vulnerability.
