Date of Advisory: ----------------- July 20th 2006 Product: -------- Chameleon LE <= 1.203 Chameleon Pro is suspected to be vulnerable but since I am cheap and not about to pay $99 for the pro version to check if a bug exists I CAN NOT confirm that the Pro version is vulnerable but can assume since it shares most of the same code.
