Background

Dropbear is a relatively small SSH server and client.

Description

A CRLF injection vulnerability in Dropbear SSH allows remote authenticated users to bypass intended shell-command restrictions via crafted X11 forwarding data.

Impact

A remote authenticated user could execute arbitrary code with the privileges of the process.

Workaround

There is no known workaround at this time.

Resolution

All Dropbear users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=net-misc/dropbear-2016.73"
