    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.
