Affected Packages:

neovim

Vulnerable:

Yes

Security database references:

In Mitre's CVE dictionary: CVE-2019-12735.

More information:

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.

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

We recommend that you upgrade your neovim packages.
