Vim < 9.2.0075 Heap-based Buffer Underflow (GHSA-xcc8-r6c5-hvwv)

medium Nessus Plugin ID 301248

Language:

Synopsis

The remote host is missing a security update.

Description

The version of Vim installed on the remote host is prior to 9.2.0075. It is, therefore, affected by a vulnerability as referenced in the GHSA-xcc8-r6c5-hvwv advisory.

 - Vim is an open source, command line text editor. Prior to version 9.2.0075, a heap-based buffer underflow exists in Vim's Emacs-style tags file parsing logic. When processing a malformed tags file where a delimiter appears at the start of a line, Vim attempts to read memory immediately preceding the allocated buffer. Version 9.2.0075 fixes the issue. (CVE-2026-28419)

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

Solution

Upgrade to Vim version 9.2.0075 or later.
