Debian DSA-4487-1 : neovim - security update

high Nessus Plugin ID 126968

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

User 'Arminius' discovered a vulnerability in Vim, an enhanced version of the standard UNIX editor Vi (Vi IMproved), which also affected the Neovim fork, an extensible editor focused on modern code and features :

Editors typically provide a way to embed editor configuration commands (aka modelines) which are executed once a file is opened, while harmful commands are filtered by a sandbox mechanism. It was discovered that the 'source'command (used to include and execute another file) was not filtered, allowing shell command execution with a carefully crafted file opened in Neovim.

Solution

Upgrade the neovim packages.

For the oldstable distribution (stretch), this problem has been fixed in version 0.1.7-4+deb9u1.
