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

Name of the Vulnerable Software and Affected Versions vim versions prior to 8.2.4968

Description The issue is related to a heap-based buffer overflow in the skip string() function of the Vim text editor. This can be exploited by an attacker to cause a denial of service or execute arbitrary code by loading a specially crafted file. The vulnerability can be triggered remotely by tricking the victim into opening a malicious file, leading to a heap buffer overflow and potential code execution on the target system.

Recommendations For versions prior to 8.2.4968, update to version 8.2.4968 or later to resolve the issue. As a temporary workaround, consider disabling the skip string() function until a patch is available. Restrict access to untrusted files to minimize the risk of exploitation.
