Title: Dart ZipLite Compression DartZipLite.DLL ActiveX Control Buffer Overflow Vulnerability
Severity: HIGH
Description:
The Dart ZipLite Compression ActiveX control is a file compression/decompression utility for Microsoft Windows.
The application is prone to a buffer-overflow vulnerability because it fails to bounds-check user-supplied data before copying it into an insufficiently sized buffer.
This issue occurs when an excessive amount of data is passed to the 'QuickZip' method of the 'DartZipLite.dll' ActiveX control.
This issue resides in the ActiveX control with CLSID:42BA826E-F8D8-4D8D-8C05-14ABCE00D4DD.
Successfully exploiting this issue allows remote attackers to execute arbitrary code in the context of the application using the ActiveX control (typically Internet Explorer). Failed exploit attempts likely result in denial-of-service conditions.
Dart ZipLite Compression ActiveX control 1.8.5.3 is vulnerable to this issue; other versions may also be affected.
Affected Products:
- Dart Dart ZipLite Compression ActiveX Control 1.8.5.3
