Yes

Security database references:

In Mitre's CVE dictionary: CVE-2018-10900.

More information:

Denis Andzakovic discovered that network-manager-vpnc, a plugin to provide VPNC support for NetworkManager, is prone to a privilege escalation vulnerability. A newline character can be used to inject a Password helper parameter into the configuration data passed to vpnc, allowing a local user with privileges to modify a system connection to execute arbitrary commands as root.

For Debian 8 Jessie, this problem has been fixed in version 0.9.10.0-1+deb8u1.

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