Amazon Linux 2023 : vim-common, vim-data, vim-default-editor (ALAS2023-2026-1539)

high Nessus Plugin ID 306194

Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1539 advisory.

 Vim is an open source, command line text editor. Versions prior to 9.2.0077 have a heap-buffer-overflow and a segmentation fault (SEGV) exist in Vim's swap file recovery logic. Both are caused by unvalidated fields read from crafted pointer blocks within a swap file. Version 9.2.0077 fixes the issue.
 (CVE-2026-28421)

 Vim is an open source, command line text editor. Prior to version 9.2.0078, a stack-buffer-overflow occurs in `build_stl_str_hl()` when rendering a statusline with a multi-byte fill character on a very wide terminal. Version 9.2.0078 patches the issue. (CVE-2026-28422)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Run 'dnf update vim --releasever 2023.11.20260413' or or 'dnf update --advisory ALAS2023-2026-1539 --releasever 2023.11.20260413' to update your system.
