The ComponentOne SizerOne Tab ActiveX control (c1sizer.ocx) is vulnerable to a heap-based buffer overflow when copying tab options. By persuading a victim to visit a specially-crafted Web page that adds multiple tabs with overly long captions using the AddTab() method, a remote attacker could overflow a buffer and execute arbitrary code on the system with the privileges of the victim or cause the victim's browser to crash.
