Vulnerability Note VU#773545
NOS Microsystems Adobe getPlus Helper ActiveX control stack buffer overflows
The NOS Microsystems Adobe getPlus Helper ActiveX control contains stack buffer overflows, which can allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.
NOS Microsystems getPlus is download management software that is used to install Adobe Reader and Flash on Windows systems. The getPlus Helper ActiveX control, which is provided by gp.ocx, contains stack buffer overflows in several initialization parameters.
By convincing a user to view a specially crafted HTML document (e.g., a web page or an HTML email message or attachment), an attacker may be able to execute arbitrary code.
Please see Adobe Security Bulletin APSB10-02. Although this vulnerability is addressed in 126.96.36.199 of the getPlus Helper control, the control is removed when the system is restarted. Therefore, it may be possible for an attacker to convince the user to install the vulnerable version of the control, even on a system that has installed the fixed control at some point. Please consider the following workarounds:
Disable the getPlus Helper ActiveX control in Internet Explorer
