FreeBSD : vim -- vulnerabilities in modeline handling (bd9fc2bf-5ffe-11d9-a11a-000a95bc6fae)

high Nessus Plugin ID 19103

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

Ciaran McCreesh discovered news ways in which a VIM modeline can be used to trojan a text file. The patch by Bram Moolenaar reads :

Problem: Unusual characters in an option value may cause unexpected behavior, especially for a modeline. (Ciaran McCreesh)

Solution: Don't allow setting termcap options or 'printdevice' or 'titleold' in a modeline. Don't list options for 'termcap' and 'all' in a modeline. Don't allow unusual characters in 'filetype', 'syntax', 'backupext', 'keymap', 'patchmode' and 'langmenu'.

Note: It is generally recommended that VIM users use set nomodeline in ~/.vimrc to avoid the possibility of trojaned text files.

Solution

Update the affected packages.
