BACKGROUND SupportSoft Inc. develops a product called Self-Service Suite which aims to help end users solve technical problems on their own. Symantec shipped a SupportSoft Inc. ActiveX control along with Norton Internet Security 2006. More information about SupportSoft can be found at http://www.supportsoft.com/ For more information about Symantec and their Norton product line, visit http://www.symantec.com/ and http://www.norton.com/ respectively. II. DESCRIPTION Remote exploitation of a buffer overflow vulnerability in a SupportSoft ActiveX control allows attackers to execute arbitrary code in the context of the current user. The ActiveX affected control can be identified by the ProgId of "SPRT.SmartIssue" or the CLSID of "01010e00-5e80-11d8-9e86-0007e96c65ae". This ActiveX control is marked safe for scripting as it is intended to be used in a web browser. When installed with Norton Internet Security (NIS) 2006, the code responsible for implementing the control can be found in "C:\Program Files\Common Files\Symantec Shared\tgctlsi.dll". III. ANALYSIS Exploitation allows attackers to execute arbitrary code within the context of the current user. In order to be successful, the attacker must persuade the victim into viewing a maliciously crafted web page. This can easily be accomplished by enticing them into clicking a link via e-mail, an instant messenger, or other means. IV. DETECTION iDefense has confirmed the existence of this vulnerability within version 6.9.545.0 of "tgctlsi.dll" as included with Symantec Corp.'s Norton Internet Security 2006. Newer versions of Norton Internet Security do not include this control. Older versions of this control are suspected to be vulnerable. Other products utilizing this control should be considered vulnerable. V. WORKAROUND iDefense recommends setting the kill bit for this control to prevent the control from loading when viewing a web page. VI.
