FKIE_CVE-2023-48706

Vulnerability from fkie_nvd - Published: 2023-11-22 22:15 - Updated: 2026-09-17 17:59
Severity
3.6 (Low) - CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:N/I:L/A:L
4.7 (Medium) - CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:H
Summary
Vim is a UNIX editor that, prior to version 9.0.2121, has a heap-use-after-free vulnerability. When executing a `:s` command for the very first time and using a sub-replace-special atom inside the substitution part, it is possible that the recursive `:s` call causes free-ing of memory which may later then be accessed by the initial `:s` command. The user must intentionally execute the payload and the whole process is a bit tricky to do since it seems to work only reliably for the very first :s command. It may also cause a crash of Vim. Version 9.0.2121 contains a fix for this issue.
