Description Laura Pardo 2018-07-20 17:36:53 UTC

The Network Manager VPNC plugin is vulnerable to a privilege escalation attack. A new line character can be used to inject a Password helper parameter into the configuration data passed to VPNC, allowing an attacker to execute arbitrary commands as root.
