The vulnerability is caused due to a boundary error in the processing of ".tgb" files and can be exploited to cause a stack-based buffer overflow e.g. with an overly long string passed via the "OpenScriptAfterUp" variable. Successful exploitation allows execution of arbitrary code, but requires that a user is tricked into adding or replacing a configuration when a specially crafted ".tgb" file is opened. The vulnerability is confirmed in version 4.65.003. Other versions may also be affected. SOLUTION: Reportedly, the vulnerability will be fixed in the next release. Do not open "tgb" files from untrusted sources. PROVIDED AND/OR DISCOVERED BY: Brett Gervasoni, SOS Labs.
