Synopsis ========
A vulnerability in NetworkManager VPNC plugin allows local users to escalate privileges.
Background ==========
NetworkManager is an universal network configuration daemon for laptops, desktops, servers and virtualization hosts.
The VPNC plugin provides easy access Cisco Concentrator based VPN's utilizing NetworkManager.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-misc/networkmanager-vpnc < 1.2.6 >= 1.2.6
Description ===========
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.
Impact ======
A local attacker is able to escalate privileges via a specially crafted configuration file.
Workaround ==========
There is no known workaround at this time.

All NetworkManager VPNC plugin users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot -v ">=net-misc/networkmanager-vpnc-1.2.6"
