Title: Ultra Crypto Component CryptoX.dll ActiveX Control Multiple Remote Buffer Overflow Vulnerabilities
Severity: HIGH
Description:
Ultra Crypto Component is an ActiveX component for encrypting and decrypting both strings and binary data.
The control is prone to multiple buffer-overflow vulnerabilities because it fails to perform adequate boundary checks on user-supplied data. These issues affect the 'AcquireContext()' and 'DeleteContext()' methods of 'CryptoX.dll'. The ActiveX control can be identified with the following CLSID: 09C282FE-7DE7-4697-9BE2-1C4F4DA825B3.
Successfully exploiting these issues 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.
