AV:N/AC:L/Au:N/C:N/I:N/A:P

Name of the Vulnerable Software and Affected Versions Vim versions prior to 9.0.2110

Description The issue is related to the parsing of relative ex addresses in Vim, which can cause an overflow when a negative line number is used. 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, and user interaction is required. A crash may not even happen in all situations.

Recommendations For versions prior to 9.0.2110, upgrade to release version 9.0.2110 or later to address the issue. As a temporary workaround, consider avoiding the use of negative line numbers in relative ex addresses until a patch is available. There are no known workarounds for this vulnerability other than upgrading to the fixed version.
