GLSA-200412-10 : Vim, gVim: Vulnerable options in modelines

This script is Copyright (C) 2004-2014 Tenable Network Security, Inc.


Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200412-10
(Vim, gVim: Vulnerable options in modelines)

Gentoo's Vim maintainer, Ciaran McCreesh, found several
vulnerabilities related to the use of options in Vim modelines. Options
like 'termcap', 'printdevice', 'titleold', 'filetype', 'syntax',
'backupext', 'keymap', 'patchmode' or 'langmenu' could be abused.

Impact :

A local attacker could write a malicious file in a world readable
location which, when opened in a modeline-enabled Vim, could trigger
arbitrary commands with the rights of the user opening the file,
resulting in privilege escalation. Please note that modelines are
disabled by default in the /etc/vimrc file provided in Gentoo.

Workaround :

There is no known workaround at this time.
