Detail
Vulnerability Note VU#630017InstallShield Update Service Agent ActiveX control memory corruptionOverviewThe InstallShield Update Service ActiveX control contains a memory corruption vulnerability that can allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.I. DescriptionThe InstallShield Update Service contains an ActiveX control called Update Service Agent. This ActiveX control is a component that is included with some InstallShield Windows software installers and is provided by the file isusweb.dll. This ActiveX control contains a memory corruption vulnerability when the ExecuteRemote() method is called using a URL that causes the web server to return a 404 error. Newer versions of the ActiveX control, which may be provided by Macrovision or Acresso, do not appear to be vulnerable.II. ImpactBy 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 with the privileges of the user. The attacker could also cause Internet Explorer (or the program using the WebBrowser control) to crash.III. SolutionApply an updateThis issue is addressed in the FLEXnet Connect 6.0 Security Patch, which is available in the Acresso support document Q113020. This update removes the "Safe for Scripting" setting of the vulnerable control, which prevents the control from being scripted by Internet Explorer. Because the vulnerable control may be provided to end-users who do not have the FLEXnet Connect SDK installed, please consider the following workarounds:
[HKEY_LOCAL_MACHINESOFTWAREMicrosoftInternet ExplorerActiveX Compatibility{E9880553-B8A7-4960-A668-95C68BED571E}] "Compatibility Flags"=dword:00000400 Disabling ActiveX controls in the Internet Zone (or any zone used by an attacker) appears to prevent exploitation of this and other ActiveX vulnerabilities. Instructions for disabling ActiveX in the Internet Zone can be found in the "Securing Your Web Browser" document. Systems Affected
