Vulnerability Note VU#362849

Adobe Form Designer and Advanced Form Client ActiveX controls contain multiple buffer overflows


Adobe Form Designer and Advanced Form Client contain multiple ActiveX buffer overflows, which can allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.

I. Description

The Adobe Form Designer and Advanced Form Client software provide multiple ActiveX controls. The Adobe File Dialog Button Control, which is provided by FileDlg.dll, and the Adobe Copy to Server Object, which is provided by SvrCopy.dll, contain buffer overflow vulnerabilities. The 5.0 versions of the Designer and Client software appear to be vulnerable.

II. Impact

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 with the privileges of the user.

III. Solution

Apply an update

Please apply the update specified in Adobe Security Bulletin APSB08-09. If you are unable to apply an update, please consider the following workarounds:

Disable the Adobe Form ActiveX controls in Internet Explorer

The vulnerable ActiveX control can be disabled in Internet Explorer by setting the kill bit for the following CLSIDs:

More information about how to set the kill bit is available in Microsoft Support Document 240797. Alternatively, the following text can be saved as a .REG file and imported to set the kill bit for these controls:
    Windows Registry Editor Version 5.00

    [HKEY_LOCAL_MACHINESOFTWAREMicrosoftInternet ExplorerActiveX Compatibility{00A2A192-4929-11D1-BA6C-080009D7FAD2}]
    "Compatibility Flags"=dword:00000400

    [HKEY_LOCAL_MACHINESOFTWAREMicrosoftInternet ExplorerActiveX Compatibility{D10E546F-3AF9-11D1-BA6C-080009D7FAD2}]
    "Compatibility Flags"=dword:00000400
Disable ActiveX

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.
