TheGreenBow VPN Client is vulnerable to a local stack based buffer overflow which can lead to the compromise of a vulnerable system. The vulnerability is caused due to a boundary error when processing certain sections of tgb (policy) files. Passing an overly long string to “OpenScriptAfterUp” will trigger the overflow. Successful exploitation results in the execution of arbitrary code.
