|
|
|
|
|
<p>When initiating a VPNC connection, NetworkManager spawns a new vpnc
|
|
|
|
|
|
process and passes the configuration via STDIN. By injecting a special
|
|
|
|
|
|
character into a configuration parameter, an attacker can coerce
|
|
|
|
|
|
NetworkManager to set the Password helper option to an attacker
|
|
|
|
|
|
controlled executable file.
