Base vector

AV:N/AC:M/Au:N/C:C/I:C/A:C

Name of the Vulnerable Software and Affected Versions Vim versions prior to 8.2.4418

Description The issue is related to the incorrect handling of a special multibyte character in the unix expandpath() function of the Vim text editor. This allows a remote attacker to access confidential data, compromise its integrity, and cause a denial of service. The problem is associated with the use of an out-of-range pointer offset.

Recommendations For versions prior to 8.2.4418, update to version 8.2.4418 or later to resolve the issue. As a temporary workaround, consider restricting the use of the unix expandpath() function until a patch is available.
