Package        : network-manager-vpnc
CVE ID         : CVE-2018-10900
Debian Bug     : 904255

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 the stable distribution (stretch), this problem has been fixed in
version 1.2.4-4+deb9u1.

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

For the detailed security status of network-manager-vpnc please refer to
