The FBI release last Friday about vishing & Asterisk touched off a bit of a fury. It now appears that they have restated their warning acknowledging Digium’s original response to the matter in question (AST-2008-003) That being, all current v1.2 and 1.4 Asterisk systems will have been patched already. Asterisk v1.6 was never effected. Digium provides further clarification as well.
