NixOS vulnerability analysis and mitigation
Overview
A divide-by-zero vulnerability was discovered in Vim versions 9.0.1367-1 through 9.0.1367-3. The vulnerability exists in the scrollcursorbot function when foldcolumn and smoothscroll features are enabled (GitHub Issue).
Technical details
The vulnerability occurs in the scrollcursorbot function where width1 is assigned the width of current window minus widths of linenumber and foldcolumn, which can be negative. If foldcolumn is enabled, width2 can be assigned 0, resulting in a divide-by-zero fault in the division operation (curwin->w_skipcol - width1) / width2 + 1 (GitHub Issue). The vulnerability has a CVSS v3.1 base score of 7.8 (HIGH) with vector: CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H (NVD).
Impact
Successful exploitation of this vulnerability could lead to disclosure of sensitive information, addition or modification of data, or Denial of Service (DoS) (NetApp Advisory).
Mitigation and workarounds
The vulnerability was fixed in Vim version 9.0.1894-1. The fix involves avoiding the use of negative width in the calculation (GitHub PR).
