Overview
The SwiftView ActiveX control and plug-in contain a stack buffer overflow, which may allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.
Description
SwiftView is software used to view or print PCL, HPGL, and TIFF files. SwiftSend is a product used for secure electronic document communications. Both of these products include the SwiftView ActiveX control and Netscape-style plug-in, which are provided by svocx.ocx and npsview.dll, respectively. The SwiftView ActiveX control and Netscape-style plug-in contain stack buffer overflows. |
Impact
By convincing a user to view a specially crafted HTML document (e.g., a web page or an HTML email message or attachment), a remote, unauthenticated attacker may be able to execute arbitrary code with the privileges of the user on a vulnerable system. |
Solution
Apply an update This issue is addressed in version 8.3.5 of the SwiftView and SwiftSend software. Please see eLynx Security Bulletin SBSV-07-10-02 for more details. |

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. Disable plug-ins Disabling plug-ins by default can prevent exploitation of this and other plug-in vulnerabilities. This can be accomplished by configuring NoScript to Forbid other plugins for untrusted sites. |
