CVE-2023-48235

16.11.2023, 23:15

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.

Common Weakness Enumeration

CWE-190 - Integer Overflow or Wraparound
The software performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control.
