Kobus van Schoor discovered that network-manager-ssh, a plugin to provide VPN integration for SSH in NetworkManager, is prone to a privilege escalation vulnerability. A local user with privileges to modify a connection can take advantage of this flaw to execute arbitrary commands as root.

This update drops support to pass extra SSH options to the ssh invocation.

For the oldstable distribution (stretch), this problem has been fixed in version 1.2.1-1+deb9u1.

For the stable distribution (buster), this problem has been fixed in version 1.2.10-1+deb10u1.

We recommend that you upgrade your network-manager-ssh packages.
