Base vector

AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions Vim versions prior to 9.0.0218

Description The issue is related to the utf head off() function in the Vim text editor, which lacks buffer length checks and can lead to out-of-bounds memory reads. This can potentially allow an attacker to impact the confidentiality, integrity, and availability of protected information. The vulnerability is due to improper validation of specified quantities in input.

Recommendations For versions prior to 9.0.0218, update to version 9.0.0218 or later to resolve the issue. As a temporary workaround, consider restricting the use of the utf head off() function until a patch is available.
