Linux Distros Unpatched Vulnerability : CVE-2026-73077

high Nessus Plugin ID 334662

Language:

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - Vim is an open source, command line text editor. Prior to 9.2.0839, the runtime/ftplugin/sh.vim, runtime/ftplugin/zsh.vim, and runtime/ftplugin/ps1.vim filetype plugins pass attacker-controlled Visual- mode selections from K through keywordprg commands without safely separating shell arguments.
 fnameescape() and PATH_ESC_CHARS do not neutralize shell metacharacters before ShKeywordPrg, ZshKeywordPrg, or GetHelp invokes bash, zsh, or PowerShell, allowing arbitrary operating-system commands to execute with the privileges of the user running Vim. This issue is fixed in version 9.2.0839.
 (CVE-2026-73077)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
