CVSS v3.1
7.8
High
| 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 9.0.0483
Description
The issue is related to a heap-based buffer overflow in the Vim text editor, specifically in the
utfc ptr2len() function. This can be exploited by opening a specially crafted malicious file, potentially allowing an attacker to cause a denial of service or execute arbitrary code.Recommendations
For versions prior to 9.0.0483, update to version 9.0.0483 or later to resolve the issue. As a temporary workaround, consider avoiding the use of the
utfc ptr2len() function until a patch is applied. Restrict access to untrusted files to minimize the risk of exploitation.Exploit
