Doc Text:
A flaw as found in Vim, 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. The impact is low because user interaction is required and a crash may not happen in all situations.

Description TEJ RATHI 2023-11-17 12:12:55 UTC 
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. There are no known workarounds for this vulnerability.
